Support » Fixing WordPress » Slow WP-Admin since update to 3.8

  • Hello everyone.
    Since the manual update I performed on my site I’ve been having ultra slow response times on my WP-Admin Site.
    I’ve tried disabling plugins and Themes by no effect. I notice it is very slow only when I am in Admin or in Admin preview of the site and the Dashboard/plugins/themes sections are particularly slow to load (but overall is very very slow)
    I have direct access to the server which I am running on my own, so no server provider here.
    Can permissions database/files hinder the performance of the admin? Since I had to re-upload some files from a backup after a failed update, I had to reset permissions on the files, but I am not sure it caused the problem.

    Maybe some tips to diagnose and solve the problem?

    Thanks everyone.

  • Me too though I’ve got a server provider.

    I’ve got 2 domains on the same server. WordPress 3.5.1 admin panel runs much faster than WordPress 3.8 on that server. Is that anyway to downgrade WordPress versions?

    tried that. check the archive. didn’t work for me.

    Does this mean I’m stuck with the slow going version until I find a fix?
    Is there any way to add some scripts to debug or diagnose the issue?

    Same problem. Any answers?

    I’d suggest starting your own threads (except the OP) as per the forum guidelines –

    Standard troubleshooting would be:

    – deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).

    – switching to the default theme to rule out any theme-specific problems.

    resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

    – re-uploading all files & folders – except the wp-content folder and wp-config.php & root .htaccess files – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.

    -Deactivated all plugins. Same performance
    -Switched to default theme: no improvement
    -Will try the last two solutions and post back

    Tried resetting plugins folder to no change.

    Resetting the plugins folder (by renaming it), renaming the .htaccess file, resetting the cache (and getting the update for that plugin) and reloading the update worked for me. I have have no idea which of these was the actual fix but I’m at regular speed now.


    probably resetting the plugins folder by renaming it did the trick. I bet its a plugin that’s sending a lot of HTTP requests and just slow to respond.

    I’m pretty sure I’m having this problem too. My question isn’t, “how can I alleviate the symptoms?” my question is, instead, “how can I identify the source of the problem?”

    I’m running this entirely on a physical linux box of my own so I have complete control. I’ve isolated that no plugins are generating extraneous HTTP requests. I’ve determined that Apache is NOT running away with RAM (at least as far as I can tell). I’ve also looked at MySQL slow queries and here’s where it gets interesting:

    I can easily see that while my site is “updating,” which seems to be a blocking event as I can’t initiate any post views during that time, that there’s a single MySQL process that goes into the ‘sleep’ state for exactly the amount of time that things lock up. The lockup duration varies from ~60 to about ~200 seconds, occasionally taking a more reasonable ~5 seconds. Interestingly the ‘info’ column for the MySQL process that sleeps is ‘NULL’. Any how I can further isolate what’s going on now? I never used to see a problem like this.

    *edit: minor clarification


    If you desire attention to this matter, do not hop on another’s post, instead, and per forum rules, start your own topic.

    Please read all of this first and note that it is also linked to at the top (sticky) post in this forum:

    My apologies! I’ll go start a fresh thread.

    did you solve the problem? i’m having the same issues, but i cant seem to re-install wp from the dashboard. it’s so slow that it doesnt even re-install and gives me error
