litespeed cache slowing down site?

    With WordPress LiteSpeed Cache plugin enabled, I’ve been testing our homepage with gtmetrix.com and I’m getting an average “D” with load time of 9.5 seconds.

    But when I disable the LiteSpeed WordPress Plugin, I’m getting a grade of “B” from gtmetrix and they are saying it’s taking 2.8 seconds.

    So with LiteSpeed WordPress Plugin DISABLED, I’m getting a 6.7 increase in page speed, and gtmetrix is giving me a B instead of a D.

    I turned the cache plugin back on for now to troubleshoot.

    I admit I am doing some fancy stuff with the LiteSpeed WordPress Plugin, including using widget ESI blocks as bullet holes to prevent certain parts of pages from getting cached.

    I’m not quite sure what I should do here.

    1. Do you have any ideas on what might causing the LiteSpeed WordPress Plugin to slow down my site?

    2. Is there something else you suggest I do to speed up site?

    Thanks for any suggestions.

  • Yes, I’ve been thinking about that lately. This issue has occurred after the last few updates.

    Hi,

    You can simply export current setting and reset to default setting and see how it goes

    by the way I see at least 16 ESI block on your homepage , each ESI block means 1 additional PHP request , so instead of you have 1 PHP request as cache plugin disabled , you make it now 17 PHP request, and that , for sure , slows down a lot

    you should only use ESI when necessary , too many ESI block will result in too many PHP request and give you adverse effect as it didn’t speed up things but slow it down

    Best regards,

    Yes, you are correct: when I disable ESI, I’m getting an “A” with a 1.6 second load time. That’s quite a difference.

    On the homepage, I thought only 3 ESI blocks were being used.

    Can you please tell me how to identify the ESI blocks in the source code? Maybe this will give me some ideas on fixing this.

    Thank you.

    Hi,

    Do you happen to use YITH wishlist ?

    you can search in HTML source code like this

    each <!-- Block uncached by LiteSpeed Cache 3.6.1 on 2020-12-23 09:49:57 --> indicates one block

    Thanks. Using some widget logic, I was able to disable the ESI blocks on the pages where it wasn’t needed. Site is now loading between A-C, with about a 3-4 load time.

    I still need to get it faster, but it is better.

    Hi,

    was that timing as cache miss or cache hit ?

    what is loading time on cache hit , with default setting ?

    what is loading time on cache hit , with default setting and only ESI enabled ?

    how many ESI block you put there ?

    seems like I was able to speed things up by hiding ESI blocks per page, and by combining ESI blocks.

    For homepage, here is gtmetrix with current settings (js, css, images, ESI – all enabled). I’m getting an A with 2.2 second load time:

    Here is gtmetrix with just default setting:

    Here is gtmetrix with just default setting and only ESI enabled:

    https://www.lifeleap.org/temppic/default-with-esi.JPG

    On homepage, I have 3 ESI blocks enabled (all needed).

    Thank you.
