Prestashop 8.1 Categories take over 30 seconds to load

[stevell]

I have upgraded from 1.78 to 8.1 but the categories are very slow to load. Over 30 seconds. If I turn on profiling it fixes the issue and the same page loads in 1245ms. 

Debug mode shows no errors.

Has anyone seen this issue or have any suggestions.

Check on Gtmetrix. Have you changed PHP version after update? Cache in VAR folder cleared?

Also whats your php setting:

• memory_limit
• max_execution_time
• max_input_time
• max_input_var

Gtmetrix times out on the category pages, so does lighthouse and PageSpeed insights.

I changed the PHP version to 8.1 from 7.4. The Cache folder has been cleared a few times.

• memory_limit 2042
• max_execution_time 300
• max_input_time 300
• max_input_var 10000

The server is CloudLinux with Litespeed although the Lightspeed Prestashop plugin is not compatible with Prestashop 8+ so not installed.

Try to enable profiling in the config/defines.inc.php file:

define('_PS_DEBUG_PROFILING_', true);

That appears to show the same profiling page as turning it on in the Advanced Parameters - Performance tab.

If I turn on profiling it fixes the issue and the same page loads in 1245ms (was 34 seconds)so it is unhelpful. I don't understand why turning on profiling fixes the issue and reduces page load time by over 30 seconds.

Indeed it is not a normal situation for the page to load faster with profiling turned on. It should take the same time + show the details.

I upgraded Prestashop 8.1 and the problem went away. I do however think it was a Litespeed issue.
