very slow admin

  • This issue has been mentioned a lot these last years and months.
    I think I have read almost all discussions and conclude a lot of WP users still have this problem of a very slow backend (most of the time).

    I have tried all suggestions, like:
    – plugins
    – map plugins
    – caching plugins
    – increase memory
    – other server
    etc…

    My site has almost 4.000 pages (no posts) and it seems WP can’t handle this (?). Who has THE solution?? Please make my X-mas!

    deleted broken link checker, optimized database etc…

    You could this a try. Only load the plugins you need for a given page ..including admin pages.

    Hi Radices,
    Thanks for your suggestion. It’s worth a try.
    I have selected the Admin part, but can’t see how to disable plugins there.

    No, I don’t think it’s plugin issue.
    I have tried
    define (‘WP_HTTP_BLOCK_EXTERNAL’, ‘true’);
    in config.php, but still no difference

    Could this PHP error be the problem?:

    Use of undefined constant ratings_shorttags_admin_scripts – assumed ‘ratings_shorttags_admin_scripts’

    wp-content/plugins/ratings-shorttags/ratings-shorttags.php:142 wp-settings.php

    What does it mean?

    something going on in your plugin called “ratings-shorttags”

    you may want to contact the plugin’s developers.

    Hi Tara,
    Yes may be something is going on with that plugin.
    I did contact the developer, but he says there is no problem that could cause the slow admin.

    BTW, do you know what this means?:
    Caller: get_pages()+ Core Rows: 3651 Time: 0,0696

    It seems the slow admin has to do with editing pages – posts don’t give problems with slow speed.

    looks like this is commercial plugin – I could not locate it in the WP official plugins directory.

    In thr OP you mentioned the site has almost 4.000 pages.

    Have you tried/considered deleting rivisons? That may spare some space.

    nope, it′s not a commercial plugin, it′s a very simple light plugin.

    yes, i have optimized my database and deleted revisions etc…

    like i have said, i have discovered the issue has to do with PAGES, with posts the backend is fast.

    Could there be a code that WP doesn’t have to ‘get_pages’ before making, editing and saving pages?

    Honestly I can’t help, but maybe I could push you, Apestaartje, into providing more accurate information, so that people that are more qualified can help you ??

    – if the slowdown occurs on precise admin pages and not others, can you please paste the hyperlink to the precise admin pages in which there is that slowdown ? You can remove your domain from the URL if you like, and start with /wp-admin/stuff, no worries

    – you checked your apache error logs, it seems. Are there other errors, or none at all ?

    – are you reaching bottlenecks in your server usage ? As we don’t know how you’re hosted, can we still know if you’re reaching the limit of your allowed CPU/RAM/disk usage limits ?
    Another possible bottleleck, mysql. Typically : you have phpmyadmin, right ? When your blog admin is slow, can you run, in phpmyadmin>SQL command, this line : “show processlist” ? if you see the mention of a lot of things queued, then that’s no good, it means your database engine fails to process everything that is required at lightning speed at it should normally be doing. That’s a test to run a good number of times, to make sure ??
    You may also see if there are lots of mysql slow queries (ask your host).

    Thanks for your response, Sabinooo.

    – The slowdown occurs on all admin pages (one time there are a few slow queries of plugins, the other time a few slow queries of other plugins and another time even no slow queries – while the admin is still slow)

    – no errors, just query_cache_size = 0 (I’ve asked my host if this is a problem)

    – no bottlenecks so to see

    Right now i’m considering to quit with new pages and try posts (without navigation and with slugs, so they will look like my old pages).
    As i’ve mentioned: using posts in stead of pages the backend is as fast as you may expect from WP.

    well the query_cache has been filled – no improvement

    I am not a programmer, but I think the delay on the backend has to do with the function get_pages.

    Anybody may be on this issue?
    Thanks.

    I can’t help more, but at least, are you sure query_cache_size at zero is reasonable ?

    I remember mine’s at something like 128M, or maybe 96M.

    If you’ve got a shell access, you may try to run mysqltuner.pl and tuning-primer.sh (I’ll let you search for them on the internet), these scripts look at what your sql config looks like, and they tell you if there are severe problems, huge bottlenecks, or they simply do suggestions regarding your hardware and current settings. They won’t change anything, only provide feedback.
