Thread:Project:Support desk/ Mediawiki Massive CPU usage tied to SiteStats.php, DeferredUpdates.php, and ViewCountUpdate.php

Recently I've been running into trouble with my web host with massive CPU usage on my wiki. I've taken steps to try and resolve this, such as installing a File cache and running the site with CloudFlare, but it still isn't enough. (Options such as using a Squid or Varnish cache are not viable as they don't work with the shared hosting model I am on).

Tech support has pinpointed one part of the massive CPU usage to "any calls to stat tracking files, such as ViewCountUpdate.php, SiteStats.php, and DeferredUpdates.php." I can't seem to find any information on these aside from the code itself, and I was hoping someone here would have information on these and what effect disabling them or modifying them would have.

Thanks. -FH14 (talk) 13:43, 15 January 2014 (UTC)
