    Hello, how are you?

    I move to lite speed server on GCP (Open Lite Speed + WordPress deployment)

    And i notice Query monitor overload the server every time i generate new page or edit him with my ¨THEME¨ (I use Mesmerize pro theme)…

    I don’t know if It’s connected to cache (we use LS Cache)

    Maybe need to exclude your plugin, but when i turn off your plugin, everything work fine.

    Your plugin in general very important and can see a lot of issues.

    But from the other hand, he overloads the server:

    1. When you Edit a page in gutenberg editor.
    2. When you Edit a page with Mesmerize Theme.
    3. When WordFence firewall running a scan.
    4. When i open couple of EDIT pages in the same time.

    Maybe need to cancel query monitor from the backend dashboard somehow? (Lite Speed use Redis for the backend + LS CACHE)

    Be happy for your help here, i very love your plugin, and he solved for me a lot of issues.

    Thanks for the report. This can be caused if your site is performing an extremely high number of database queries, PHP errors, translations, HTTP API calls, etc. In this situation, Query Monitor can cause memory exhaustion by the sheer amount of information it collects.

    Opening multiple pages at the same time shouldn’t come even close to overloading the server, if it does then your server is operating at too close to its maximum capacity and you’ll need to look at increasing the memory limit.

    Your best bet is to use the information that QM shows you to address performance concerns, for example by using the Queries -> Queries by Component panel to see which is the worst performing plugin or theme and going from there.

    Good luck!

    Yeah, database is the first to fall down on the server.

    What i can do, It’s to turn off the plugin when editing pages.

    But still, when WordFence firewall run a scan, server struggling.

    Without QM server running very good…

    It maybe can be cache problem with LS Cache plugin?

    You maybe have recommendation to exclude some QM scripts/css from the cache?

    Another thing i was thinking, maybe turn off the plugin and use it only when you want to check something? (turn it off, its mean not from the plugin section)

    i know you can keep the plugin active and add the wp-config:

    QM_DISABLED

    or

    QM_NO_JQUERY

    If you can do it in a click of a button without turn off the plugin in the plugin section, it can be useful.

    In the same time, it will save memory and people not need to invest a lot of money on VM and Memory… site should be cheap,
