Hi everyone ! I could use some help. I'm using Prestashop 1.7.7.7, and since a few weeks, I'm experiencing a really slow back office (10 to 20seconds between pages). I have no issues with the front office. I upgraded to a faster server (doubled the CPU/RAM), but nothing changed. Trying to know which module or hook could be responsible for this slowness, I enabled debug mode to have timings on the request. And in debug mode, the back office is super fast. I don't have the same issue at all. I already tried to clear the 'prod' and 'dev' cache, my smarty recompilation settings are on "never recompile". I'm a bit clueless right now, do you have an idea what could case such a difference between debug and prod modes ? My first idea was to enable debug mode as it enables performance monitoring using Symfony, but as I said, debug mode seems to "solve the issue"... It is obvious that I just can't let the shop in debug mode while in production, so I must find the real issue. Do you have ideas for me to dig deeper ? Thanks a lot 😄

Hello! I'm new to PrestaShop and I'm evaluating if it is a good product for my needs. After reading all the documentation I've found, there are two topics that rise some doubts about PrestaShop: scalability and high availability. I have some concerns regarding those topics, and I would be very pleased if someone could answer any of my questions, or point me to the right direction to look at: Are there any "big" shops using PrestaShop? By big I mean shops with more than 40.000 visitors per day and/or 5.000 orders per day. (I've read http://www.menlook.com/, any others?). In case these shops exist, I imagine that they have more complex installations than the "single server" approach. Is there any official documentation about installing PrestaShop for high availability environments, that is, with a different topology than a single server (clustering, load balancing, etc)? I come from the Java world, and the web applications usually have official documentation related to clustered installations. Summary: is there official documentation about installations with more than a single server? If not, does the PrestaShop team plan to add that kind of documentation to the existing one? My other concern is about scalability. I have not seen in the documentation nothing about how to scale PrestaShop, or about how adding more servers improves the total amount of concurrent users/orders PS can handle. Imaging a scenario where users and orders keep growing during time, there is some point at which one or two servers obviously can't support the traffic. A benchmark would be useful to see wich kind of resources are necessary for very large shops and to know which is the traffic that can be handled with a server. Summary: is there official documentation about PrestaShop performance benchmarks? If not, does the PrestaShop team plan to add that kind of documentation to the existing one? In general, my concern is about how far can PrestaShop go, and I have'nt found documents about these topics. Thank you so much for your attention. Hope to use PrestaShop in a short time!

Bonjour, Je viens de voir que ma note google speed est fortement descendue (42), alors que mon site ma parait toujours rapide. D'autant plus que je ne comprend pas les améliorations à apporter ni comment faire... De mon côté, le site me parait rapide, même si je le teste en navigation privée pour éviter les caches de mon navigateur. Alors je ne comprends pas cette note...et en plus, internet n'est pas super rapide chez moi... Est-ce- quelqu'un peut tester mon site et me dire l'impression que ça donne svp? Merci d'avance et bonne journée

Hello, I need some help. I've been struggling past few weeks with improving SEO of my shop, including technical side as suggested by PageSpeed Insights. I've managed to improve a lot, but it's still far from good, especially on mobile. Links: PageSpeed Insights - Shop's main page PageSpeed Insights - Example category site PageSpeed Insights - Example product I'm mostly struggling with eliminating render-blocking resources (jquery especially, how do I delay it?) and reducing unused JavaScript, which seem to slow down my FCP and LCB on mobile devices significantly. Would any kind soul give me some hints on how to improve further? Cheers

Hi all, Just in case anyone needs, here's a tiny python script to warmup prestashop cache. It fetches all the links from the sitemap page of your site and downloads them. Usage: python warmer.py http://example.com/sitemap where example.com/sitemap is the address of your site's sitemap page. https://github.com/tonage/presta-cache-warmer/blob/master/warmer.py

Hi, I'm upgrading my shop from 1.6 to 1.7.6.9. I'm on the last phase of the process (working locally and on a test server) and I was trying to optimize a performance issue in the loading of some products. Looking at the profiling data for those product pages I found a huge amount of repeated sql queries, which seems to be the problem. I'll attach a few screenshot of the profiling log and the full log itself. Note that this isn't even the worst case, this loading can take up to 4 seconds, with even bigger numbers on the same queries. Now even looking at the products that seemed to load normally I found the same repetitions (in the order of tens instead of hundreds), so I'm starting to think this is a widespread problem, but I still can't understand what causes this and why it is much worst on some products. A few notes and things I tried: deactivating non-native modules doesn't make any difference i have no overrides on core Prestashop functionality enabling/disabling/clearing the cache doesn't make any difference when profiling any front office page I got a "malformed number" error, commenting out the inciminated line of code in the profiler php script the problem was circumvented (i think this caused us to lose the hook and module info, everything else seems fine). Doesn't seem plausible, but could this be related? Note that the severity of the problem changes between products, but a super slow to load product stays slow. I didn't include it in the screenshot for spacing reasons, but the profiler for ObjectModel instances shows a lot of duplicated instances of /classes/Link.php and /classes/Product.php Being fairly new to Prestashop I'm not even sure how to approach this at this point. Can anyone help or at least give me some ideas on how to debug this? Kind regards, Andrea product-load-full-log.txt

[MODULE] Advanced product customization-Reuse attribute display Module Overview Expand the built-in product customization and add many form controllers: Select (Drop-down list), Radio, Color or texture, Email and other H5 elements. Supports the reference of product attribute combinations, additional price and weight additions. What this module does for you directions_car Customize your online store This module solves 3 big problems: When there are more products or more product attributes, a large amount of product attribute combination data will be generated, which will eventually cause the PrestaShop website to become very slow, causing customers to lose the patience to place orders and lose customers. PrestaShop's built-in product customization only supports two types of text and uploading pictures. Based on this, we have expanded the 3 commonly used form controls: Select, Radio and Color or Texture (supports custom uploading of pictures): simple, flexible and high- performance. Support for setting the price and weight of customized products. Using our module, you can easily create high-performance product attribute customization combinations without any performance problems, and you can reuse the attribute data you already have, without increasing your maintenance costs, and saving you a lot of money Precious time. What your customers will like 1.Customers do not need to worry about insufficient inventory. 2.Customers can customize the products they need at will. They don’t need to bother to fill in the requirements one by one, and simply select from the existing attributes. This brings 2 benefits: The customer's customization needs are more accurate, and communication costs will not increase due to arbitrary remarks, saving valuable time for both parties. Direct selection is far better than filling in one by one by customers, which saves customers a lot of valuable time and improves order conversion rate.

Saya mau berbagi apa yang saya lakukan untuk mendapatkan performa prestashop yang optimal. Berikut skor google page insight web saya: Mobile score: Desktop score: *Untuk skor mungkin bisa berbeda², untuk memastikan real score lakukan 2X test (karena ada faktor page cache) 1. Teknologi server/hosting yang saya gunakan: PHP 7.3 + Nginx + MariaDB (semua versi terbaru) 2. Cloud hosting pakai upcloud (data center singapore) dan server management pakai runcloud 3. Internal prestashop: - theme pakai yg ringan dan teroptimasi, saya pakai theme classic rocket, ada di official github prestashop - hanya pakai module yg perlu saja, module ga terpakai di nonaktifkan - module tambahan (berbayar) yg saya pakai untuk optimasi: page cache pro & google webp images generator Hanya itu saja yg saya lakukan, tapi prosesnya agak detail dan panjang ya. Jadi hasil akhir masing² juga bisa beda². FYI saya hanya merchant bkn programer. Dan saya yakin cara saya diatas masih bisa di maksimalkan lagi. Mungkin bisa saling menambahkan tips lainnya === Update 15 Mei 2021 1. Teknologi server/hosting: Native Nginx -> Litespeed Web Server 2. Cloud hosting pakai upcloud (data center singapore) -> Vultr High Frequency Compute 3. server management runcloud -> cyberpanel 4. Internal prestashop: - theme pakai yg ringan dan teroptimasi theme classic rocket -> warehouse - hanya pakai module yg perlu saja, module ga terpakai di nonaktifkan -> sama - module page cache pro (berbayar) -> Litespeed Cache (free) - module webp images generator (berbayar) -> sama Hasilnya sangat memuaskan

We have a shop that runs on Prestashop v1.7.5.1 and the site becomes extremely slow once we add a product to the cart. Also, when we apply a coupon it takes about 10-20 seconds to apply it. What we tried We enabled CDN (cloudflare) , we also enabled server side caching. In the Prestashop the CCC is enabled for HTML & JS & CSS and we now have enabled the CacheMemcache. However, none of this seems to fix the slow checkout process. Ajax cart is enabled but still customers are reporting 10-25 seconds to complete each step. We then tried to enabled the profiler and found strange values. So, we are guessing it is something wrong with the theme itself. Since the log is huge. We are sharing few value and file is attached. We need help understanding what does these values mean. Profiling numbers from the site are below Querying Time 6119 ms Queries 1821 Memory Peak Usage 47.0 Mb Included Files 625 files - 8.66 Mb PrestaShop Cache 0.01 Mb Global vars 0.38 Mb Top 5 Table Stress 912 category_lang 900 category 673 category_shop 193 creativepage_meta 124 cart_product ObjectModel instances Name Instance Source Category 1554 /modules/posmegamenu/posmegamenu.php CartRule 50 /classes/Cart.php Carrier 22 /classes/Cart.php Load Time.docx

Hi there, on sunday we are launching a prestashop with around 50.000 products. We will grade up to around 150.000 products within the next 12 weeks. All products have around 5-15 attributes. We have heaps of variants, but do not use the variant functionality of prestashop. It is disabled. We have them in a seperate system and only rendering a variant configurator via elasticsearch on the product page that then redirects to the proper product details page. Everything works pretty fine, except the performance of the product category/ listing pages. Especially when the category has lots of products. Product detail page performance is awesome! One category has around 40.000 products, and the page loading time is around 3.5 s which is way too slow. I gave everything I found so far a try. It's not related to php (7.2), debug mode, profiler, caching or something else. Also when I disable the category tree and the faceted search module I do not get much better performance. I see that even if I load 24 products per page, there is around 120 queries against product page. When I enable faceted search module, there is around 4000 queries per page load. probably related due to our amount of attributes. Does someone have a idea what to do? The only chance I see so far is really overwriting the core code with my custom queries or use elasticsearch to render products on client side. Maybe someone of the presta core team if there is a chance to fix this in prestashop? Would really appreciate your help! Thanks a lot, riu

Hi guys, I am struggling to fin the maintenance under the performance page while I am trying to disable shop in order to perform upload back_up version of the DB. I ma using PrestaShop 1.7.3 That's what it says in documentation on the PrestaShop when creating the back_up Set "Enable Shop" to "No" in the "Maintenance" page under the "Preferences" menu. However, I cannot find the maintenance section. Any suggestions? Thanks

I have my own server, with 26 Gb RAM dual Xeon and what it will be a small bakery site and some small sites (WP). Not really significant traffic, but I want to be as fast as possible in serving the pages. Many info I've read are for previous versions of Prestashop, I have the newst version (1.7.6.4) I run on the server CentOS 7.7 Server software version: Apache 2.4.6 PHP version: 7.3.16 Memory limit: 512M Max execution time: 300 Upload Max File size: 128M info_outline Database information MySQL version: 5.7.29-32 PERCONA (INNODB) MySQL server: localhost MySQL engine: InnoDB MySQL driver: DbPDO I've installed Opcache and PHP 7.3 and configured like in the tutorials. I've also installed php-pecl-apcu module (caching) php.ini [Date] date.timezone = UTC [Session] session.auto_start = Off [PHP] short_open_tag = Off display_errors = Off magic_quotes_gpc = off memory_limit = 512M max_execution_time = 300 max_input_time = 300 upload_max_filesize = 20M post_max_size = 22M max_input_vars = 20000 allow_url_fopen = on opcache.ini opcache.revalidate_freq=0 ;opcache.validate_timestamps=0 - still developing, not production opcache.enable_file_override=1 opcache.interned_strings_buffer=64 opcache.memory_consumption=256 opcache.max_accelerated_files=20000 Quick questions: 1. Smarty cache: yes/no 2. If YES -> Caching type: File system or MySQL (Percona) 3. Use cache (CacheApc): yes/no (remember, I have OPCache) 4. Do I still need to visit each page of the site in order to create cache (script based on sitemap.xml)? 5.

Why is my site running soooo slow?!? I have a custom theme on the site, but even with the default Prestashop theme it's so slow to load in every page – including basic pages such as about page. I know that I can benefit from adding a good caching module, but would site really be this slow even without the module? Simulating on pingdom.com takes 19 seconds to load the index page. 19 seconds!! images are not that large, and even if I disable the modules that use images, it does not help any. My server specs are : RAM: 19GB PROCESSES 1,500/min MEMORY: 768MB PHP VERSION: 7.1 See the attached image from pingdom – the long yellow wait time is for the index.php file In the backend I'm really confused how to setup the performance page... I read some blogs saying that Smarty caching is bad for performance, some say it is good. See the other image of the setup in my performance page. Any feedback would be greatly appreciated. Thanks.

Hi, Recently my hosting provider has added the new version of PHP 7.0. I tried it. So, here are my feedback (can be individual in your case). Performance: The site began to work better in form of speed. A bit faster response. Faster back office performance, product saving, etc. Problems: Started to get error 500 in the back office. This happens only when saving some preferences/admin. But everything works fine in products or categories. Has anyone else tried PHP 7.0 ?

Hi, Most of the tools like GTMetrix show our site www.absolution-cosmetics.com running and loading at a good speed at around 1 to 3s from their London server for https://www.absolution-cosmetics.com/fr/ pages. However we have numerous visitors who are letting us know about serious slow loading times. One thing I notice is how slow the PS scripts can run on the cart page which is an OPC, when we change quantities, log in, choose a carrier. Has anyone some ideas what to look for, issues or solution wise? Thanks

Hi, i wanna use media servers on page www.lezecky.sk. http://www.webhostinghub.com/help/learn/prestashop-15-tutorials/performance-and-security-15/setting-media-servers-performance I created 3 subdomains: http://sub1.lezecky.sk/ http://sub2.lezecky.sk/ http://sub3.lezecky.sk/ On every subdomains i created statics folders (themes, css, js). And now i use media servers. (Advanced Parameters -> Performance) All work ok, static data are downloaded from diferent domains, but it`s not what i want, because now i have duplicated data on every subdomain, and it`s hard to keep data actual on every subdomain. After every each change (for example add new product) i have to reupload data to every subdomain. How can i setup subdomain, to get static folders from parent page (www.lezecky.sk). Can i use .htaccess for setup, or is there any setup proces? Can somebody show me some example, or setup .htaccess file for each subdomain? Thanks guys

Hello everybody, I tryed to transfere my prestashop 1.7.3.1 website for a server to another server (I followed some tutorials to do that and it worked well). All is OK except one thing, I can't access to "Advanced Parameters / Performance" page, it says Error 500. But when I activate manually Debug Mode by changing config / defines.inc.php -> define('_PS_MODE_DEV_', true); Performance page becomes accessible, I don't want debug mode to be enabled all the time. How can I resolve this please. Thanks in advance

I make a blog module and now comes the pagination issue where I need the rows count for the respective calculations. I have an idea to make a table lets say category_total where I will have 2 columns (category_id, total) where I will update the total once I add or delete something. I will delete the row only if the respective category gets deleted from the system. Is it a good approach or you have something better in your mind? Thanx for your valuable time

Bonjour, Je n'arrive pas à sauvegarder les changements au niveau de la page Paramètres avancés > Performances Merci de m'aider à trouver une solution

Bonjour à tous, J'ai créé un petit tutos expliquant comment optimiser son site : https://www.nemesis-tech.com/optimiser-les-performances-et-chargement-de-prestashop N'hésitez pas à me dire si vous avez des "trucs et astuces" et vos retours d'expérience afin d'aider la communauté ! Merci à tous !

Secondo voi Prestashop riesce agevolmente a gestire e visualizzare dieci/quindicimila articoli con un piano hosting condiviso o consigliate vivamente un VPS. La domanda sarebbe: rischio e continuo col condiviso (in U.S., ping 130 ma SSD) e poi si vedrà oppure passo fin da subito al VPS? Mi preoccupa il caricamento del csv che anche se suddiviso tra Prodotti e Combinazioni, in totale è di 13mb

Hallo zusammen, geht um eine Presta Installation die auf dem Server von 1&1 läuft. Im Presta Shop soll unter Configure/Advanced Parameter/Performance (ganz unten letzte Option) der "Smarty Cache" aktiviert werden, dafür sind aber PHP-Zusatzfunktionen notwendig an die man offensichtlich bei 1&1 nicht einfach so rankommt. Schaut bitte mal in den Screenshot im Anhang. Wie bekommt man in einem 1&1 Paket eine dieser vier Optionen aktiviert bzw. installiert ? Ist das eine kostenpflichtige Zusatzoption ? Leider sehe ich nirgendwo die Möglichkeit eines der vier Möglichkeiten in dem Paket zu installieren. Über eine Antwort wäre ich Euch sehr dankbar.
