Slow cache functionality

    Hello,

    I have a strange situation with litespeed cache and the problem is that is taking a lot of tine on the server to process the information and store it into cache.

    I’ve monitor the load of the pages with x-ray and the only 2 issues that I have are

    Issue name Type Duration (%)

    WordPress/litespeed-cache Module/Plugin 66.805% (2.605 sec)

    ob_end_flush System function 41.748% (1.628 sec)

    If I disable the plugin then the website is faster.

    If a page is cached then everything is fast, so delivery from server cache to browser is very good.

    I’ve had multiple discussions with hosting support team for this and they’ve made update to litespeed 6.1 and still the same issue.

    As features that we are using are:

    • Browser cache complete
    • Object cache => in Redis
    • webp image replacement (all images are already webp)
    • cron managed by WP Toolkit from cPanel
    • Public cache complete
    • Private cache complete

    One last thing that I want to mention is that we have aproximative 3.800 products

    The page I need help with: [log in to see the link]

    First of all you have completely wrong settings for browser cache. Never enable browser caching for dynamically generated pages. This always displays stale content. Remove that configuration and try again.

    this is normal , our plugin will use ob_start() to buffer the output , this means it is hook into system as soon as possible, after wordpress initialize the plugins and finish the output buffer at end of process, so basically this function is running as long as most of page generation life cycle

    2 things you could try , 1) disable ESI if you have that enabled , 2) disable object cache , some times the object cache could even slow thing down

    Hello,

    @serpentdriver => I’ve done this and the speed improved. Thank you

    @qtwrk => ESI was disabled and with object cache disabled is much better.

    I will monitor it for one more week and come back on this ticket with a feedback.

    Thank you very much for your help and settings feedback, it helped!
