Jetpack causing high load (4 posts)

    Hi!

    We just enabled Jetpack on our site and noticed that the load on the server went from around 10 to 80 causing failure to connect to our MySQL database.

    We use the great tiled galleries function on several articles, and it looks like this is what dragging our database down (we installed it the 23 of January, and this is what our mysql log look like: http://i48.tinypic.com/ih058l.jpg ).

    Any recommandations? We would love to continue using the tiled galleries on our site, but would also love to have the site up and running :)

    Tiled Galleries shouldn't create any extra database queries on your site: the Tiled effect is managed by WordPress.com, and shouldn't bring any extra load.

    Could you try the following:

    1. Install and activate the Debug Bar plugin
    2. Add the following constants to your wp-config.php file:
      define('WP_DEBUG', true);
      define('SAVEQUERIES', true );

    You will then be able to monitor the queries and find out which ones are slowing down your site.

    I would also suggest adding a caching plugin to your site, like WP Super Cache.

    I work with Kim on the same site. Added debug bar and ran it on a post with a tiled gallery, and it looks like wp asks over and over and over again for the same info? This is on a site running w3 total cache and varnish.

    See queries here:

    (we might disable jetpack before you see this)

    I was wondering if it could be related to ms_files_rewriting somehow? http://core.trac.wordpress.org/ticket/19235

    Hi!

    We ran some tests to try to understand the issue, and we wonder if the problem could be linked to W3 Total Cache.

    Could you try to disable the W3TC Object Cache module and test the site, then turn that module back on and switch off the Database module

    If turning the modules off independently doesn’t help, could you disable them both and try again?

    Thanks!
