WordPress site takes 10-30 seconds for the first byte to download

    The site hasn’t always been slow like this, it just started happening, and I don’t know what could have changed to provoke the slowness.

    The site gets a B for a YSlow score.. it doesn’t seem to be an issue of optimization. In fact, it takes more than 10 seconds for the site to even begin doing anything when the homepage is requested.

    I’ve migrated it here so I can beat on it without disrupting the live site any further: http://gstudio.ebhost.net

    Once the site begins to download, it moves along just fine.

    I have disabled every single plugin, and it’s still slow. Plenty of other people using the same theme without issues, but I guess I will mention that changing the theme to Twenty Twelve speeds things up, but that’s probably only because the site is no longer doing anything at all, just showing a blank page with a menu at the top.

    I’ve tried moving the site to a dedicated server at a different host, and no improvement.

    So, WordPress people, where do I go from here? What tools are available for troubleshooting this issue?

    If I’m unable to figure this out, where is the best place to purchase paid support?

    Strange.

    Weird indeed!

    I recommend jobs.wordpress.net for paid support!

    I have confirmed that it is a theme issue, but apparently it’s only an issue if you have thousands of users as this site does.

    The theme ran multiple queries on every user to populate the page with content. The theme developer will release an updated version with a more efficient method retrieving the necessary data.

    I noticed earlier that a source page looks horrible, but i didn’t want to break your confidence

    Just to get the whole picture, could you add this line in the footer of your theme to find out how many database queries a page is making:
    <?php echo get_num_queries(); ?> queries in <?php timer_stop(1); ?> seconds.

    Place it for the default theme as well, see the difference.
    Don’t forget to clear cache and cookies after switching themes.

    Let us know.

    The problem has been resolved. With more efficient code for getting the homepage data, the site now generates 119 queries and completes in 1.2 seconds.

    I should mention that before the changes to the theme were made, it generated 14,300+ queries to render the homepage.
