    Hi,

    since a few days my site is slowing down from time to time. Even though I did not change anything, but of course updates were happening and I don't have x-times more traffic.

    In the php-slow-queries log there are following errors. 

    What's the reason for that?

    Thanks a lot for your help!

    Hi!
    When you say your site is “slowing down”, are you referring to the public-facing side of your site, or does this happen when you are logged into your admin dashboard?

    Looking forward to your response.

    Regards.

    Hi,

    the public side. The backend for admins is always a little bit slow…

    Thanks!

    On checking your site, everything looks good, and the performance test appears to be excellent, except for mobile.
    Have you done the performance comparison on your site with and without WPO active? If not, please do, as this will help ascertain if WPO is slowing down your site or improving its speed.

    If you experience a reduced performance from the results, they we can proceed from there to see what can be optimized further.

    Looking forward to your response.

    Regards.

    Of course it’s improving performance, but not as much as I need to. Especially on mobile I always get bad page speed results from Google and therefore I need to do something. And on top of that it produces those slow queries and my site is even accessible ☹️

    And of course I did everything and invested hours and hours on improving it and tuning the configuration. Some things – especially JS minifying – broke the site and I needed to go back. Also excluded some scripts.

    Of course cache, images compression, everything I use.

    At the end it’s not satisfying and I need to find a better solution if it’s not working. I’m loosing to much mobile traffic because of that.

    Do you have merging enabled, your site supports http2, do not enable merging for CSS/JS

    Minifying can be tricky, you will need to find the files that are causing issue and exclude them from processing. Unfortunately, some plugins/themes do not like this.

    It may also help you defer the loading of some of your JS files.
