WordPress MU – Creating a site takes ages

  • I have 2 dedicated servers. I have WordPress MU on both. When I try to create a site

    1. WP MU 1 on server 1 does it in 3-5 seconds
    2. WP MU 2 on server 2 does it in 45-50 seconds

    What can cause this delay? How can I debug PHP and MySQL?

    PS: Both WP MU are test installations. No plugins activated. Both OS are CentOS, Httpd is Apache and DB is MySQL.

  • Have you tried taking all the plugins out of the plugin folder and same with the themes?

    Even though the plugins aren’t activated WP still scans through the files. I would start there and run another test.

    Other then that I would run a phpinfo and compare the two server configurations to find what the difference is or try a 3rd server just to make sure it’s not the codebase. If the codebase is exactly the same then it has to be a server config issue… take a closer look at php accelerators as well.

    Hi Bart,

    The only difference is slow one has PHP 5.4. The other one is 5.3.

    Servers have identical setups? No memcached or apc on either?

    Also which is the slow one? Php 5.3 or 5.4?

    Dear Mika,

    No, server are not identical. The one which has PHP 5.4 is slow at creating a subsite. And this server has a better cpu and more ram.

    Given my anecdotal tests on php 5.4 are much faster…. I would think something was set up weirdly on the server. Is new site creation the only super slow aspect? Have you checked error logs on the server?

    Dear Mika,

    Yes. Posting, creating new user, etc. are working fastly. Which logs should I read?

    The server error log (there’s usually just the one for the account, error.log or such). It stores PHP errors, 503s from mod security and htaccess, etc.
