Prestashop 8.2 Admin Backend SLOW

[webbrent]

Hi Everyone,

I have multiple 8.2 installations that seem to have just gone haywire overnight. The front-ends are responsive and processing of orders is quick and without issue. It is however when accessing the admin back-end that the performance issues are being experienced.

I have multiple hosts with multiple various installations. Anything below 8.2 is not experiencing any issues and is super responsive.

I am seeing a lot of API calls received as per below in the logs - I am wondering if these instances of Prestashop are not trying to communicate with a Prestashop API of sorts which is problematic or experiencing an outage? It seems to be very haphazard and seems to have spurts where it is okay momentarily and then just reverts back to slowing down.

API Call received = /adminXXXXXXXXX/index.php?controller=apiSecurityPsMbo&token=XXXXXXXX

Any advise or assistance will be greatly appreciated.

Just to add, I have various other installations on the same host including 1.7.X and 8.1.2 installations and all of them are without issue.

A customer contacted me with the same problem. Here is his latest response.

Prestashop uses unpkg .com as a CDN for the back-office template assets. The CDN is currently down, as you can see https://www.unpkg.com/status/ . It should come back up soon, I guess they are working on it.
I disabled the new theme, since the old theme has all the files hosted on the server and is not affected by unpkg CDN issues. Once it is back we can use the new theme again.

I am assuming they have a separate CDN then per instance of Prestashop available as this is only effecting 8.2 instances?

maybe they changed from local to cdn from 1.7 / 8.1 to 8.2?

in 1.7 there is a CDN request to this address: cdn.segment.com / none from unpkg

I have a 8.1 client that has no issues - it is only 8.2 that is effected thus far.

Shocking that a stand alone instance has to be dependant on an external CDN to operate efficiently.

 

i know previous versions we used to disable comms with addons.prestashop to prevent these kind of performance issues and delays when addons.prestashop was experiencing latency issues.

Seems to now be sorted out, but was not a great thing to wake up to on a Saturday morning.

They are also doing some tracking with these CDNs like google analytics and stuff, yeah pretty bad for a "stand alone" instance but as many open source products that had some success they steer to commercial-mostly very fast.

Seems like the CDN is problematic again today.

Is there anyway to disable this? Or better yet, should it be disabled?

I found the codes from unpkg.com in the PS Account module. I removed them from several files, but then I couldn’t open anything, so I restored them, and now it works, but slowly. PrestaShop caches some files on unpkg.com, and since the server went down, the shop goes down as well.
