How to find the culprit

    So I’ve installed query monitor to find out what slows the backend and the frontend down. The frontend is not so much a problem because it’s cached however page loading times on the admin dashboard are 10s, thats also what query monitor reports however, how do I find out which plugin or php script is causing this.
    There are reports of two slow querrys however in the last tab the time is said to be 0,5s for that querry.
    Is there a log which I could post so someone could check it and pinpoin the problem?

    Best regards

    Firstly take a look at this guide: https://querymonitor.com/docs/how-to-use/

    If nothing in that list contributes to a large portion of the page generation time in the admin area then unfortunately you may have a problem that cannot be detected at the PHP level (eg. with Query Monitor) and you may need to investigate this with a tool such as Xdebug or XHProf, both of which require a PHP extension to be installed.

    Before you do that though, you should try simply deactivating your plugins one by one to see if there’s an obvious culprit, and speak to the corresponding plugin author if there is.

    I’m writing an article about debugging the things that QM can’t help you with. Hopefully it’ll be ready soon.
