Page speed: extremely long response time and admin-ajax.php

  • Hello,

    I have a screenshot from my chrome dev tools:
    https://ibb.co/jwjatd

    It looks like the first line called: “nameofmywebsite.com” (just 18kb) took 4.87 seconds just for the response time! Is that a problem that could be related to the hosting or to wordpress? What would be the best procedure to diagnose it/solve it?

    Also, there is this file called admin-ajax.php (just 603 bytes) which took a lot of response time. Do you know what is that file for? is it normal that the server is taking so long to respond?

    Thank you

    The site loaded in less than 2 seconds for me… that is fairly normal.

    Can you get it to be faster? Possibly but it will depend on many things such as who your host is and what third party scripts such as google analytics code you are using. Also worth noting that I have experienced slowness before when logged in as an admin but then when visiting site as normal visitor it will be much faster.

    admin-ajax.php (just 603 bytes) which took a lot of response time.

    this is code that is usually only used only when users are logged in and yes, it can slow the site down. However, in my experience it is usually not the reason for sites being slow as much as tests might make it appear to be. If you want to disable it take a look a this article from siteground for info about how you can do so.

    Hope this helps.

    You’re right! But why some wordpress sites are still fast whan I’m logged into admin? This one is so slow when I am logged! Do you know what could be the problem for admins?

    When logged in there are many factors…. My first question would be are you using a caching plugin or CDN? If so, something may be configured in correctly.

    Yes, I do actually!

    Something like what could be configured incorrectly?
    How can a caching plugin or a CDN slow down the backend?

    It’s hard to say what is misconfigured… but typically what I find is that people are using more than one caching plugin when they have the problems you are describing and the code from the two plugins is conflicting with each other. Some caching plugins as if you want to cache pages for admins and or logged in users… typically you do not want to be doing this but there are situations where you may want or need to in these situations you need to be sure that you are configuring everything a specific way.

    Which caching plugin(s) are you using? I might be able to pin point the misconfiguration if you tell me which plugin you are using.
