Prestashop 1.7.2.4 horrible performance

[knl]

I have been stress testing WooCommerce and Prestashop in order to determine which shop system would best handle a lot of requests. I have created a simple setup with one category and two products which I have then tested using the Apache AB tool.

I have tested Prestashop both with and without Memcached and in both cases it performs absolutely horrible with huge amounts of failed requests.

Running with 5 simultaneous connections 5000 times I get:

WooCommerce without memcached: 542.424 seconds 0 failed requests.

WooCommerce with memcached: 5.910 seconds 0 failed requests.

Prestashop without memcached: 252.263 seconds 4995 FAILED requests.

Prestashop with memcached: 244.485 seconds 4956 FAILED requests.

 

I have validated that Prestashop (PHP) actually uses memcached and it clearly shows in "top".

Eventhough memcache is active it doesn't help Prestashop with its performance issue and the PHP/Apache log shows 0 errors.

 

Am I the only one having these horrible results?

UPDATE: I have also tested with more moderate setting, but I am still getting the same results. I then decided to test the last 1.6 version. It performs better than 1.7, but also has huge amounts of failed requests.

UPDATE 2: The first test was performed on Apache. I decided to test on Nginx and while that helped, Prestashop still performs horrible with many failed requests.

Time taken for tests:   22.565 seconds

Complete requests:      1000

Failed requests:        761

I decided to also run this against Magento:

Time taken for tests: 175.500 seconds

Complete requests: 5000

Failed requests: 0

 

Opting out of Prestoshop.
