 * Every host I go with, they always say my CPU usage is too high. I’ll tell you
   a bit about my site, please help me fix the problem:
 * Plugins:
    Adsense Manager Akismet Cforms II Cystat Feedburner FeedSmith Full 
   Text Feed Google Analyticor Google XML Sitemaps Gregarious gunnART Alphaindex
   HowtoGeek – Spam Filter JAW Popular Posts Widget Official Comments Optimal Title
   Popularity Contest Subscribe to Comments Text Link Ads Wp-pagenavi Wp Super Cache
 * I need most of these plugins so I can’t really disable them =(. I get about 5400
   + pageviews daily. The site is [http://vistarewired.com](http://vistarewired.com)
   if that helps.
 * Do I need to go on a semi-ded?
 * Thanks for your help.

 * Hi,
 * It’s probably wp-cron.php.
 * If that file is running on a schedule, too often, a host will “freak out” because
   it can really smack their CPU usage, hard.
 * You can disable wp-cron.php and set up a cron job for it, so you can moderate
   how often that file calls the server.
 * If you use Cpanel, just go into Cron Jobs and enter the Command line to point
   to wp-cron.php, then tell the server (via the Cron Job Options) how often to 
   call the server.
 * Some people have had wp-cron.php calling the server every 15 seconds, WITHOUT
   REALIZING it was even happening… until their Host said “Hey, CPU is too high.”
 * Anyway, I have mine set to run once a day (in wee hours of morning/US time).
 * I personally don’t know of any other file that hits CPU as bad as wp-cron.

 * What do I enter in the command field that would point to wp-cron.php?

 * What exactly does wp-cron.php do? And I have the same question as thelocomon.
   Is this file necessary?

 * I’ve just been bitten by the same issue. My host shut off a wordpress folder 
   because the CPU usage was hogging up the server. I had 16 active PHP processes,
   all apparently busy with index.php.
 * Some threads point to shutting out the spawn_cron() call and replacing it with
   a regular system cron job (see [here](http://wordpress.org/support/topic/124485)).
 * Does anyone know for sure what is causing the CPU load (loop, timeout, resource
   access, crons spawning on top of one another)?

 * how do we find out if wp-cron is in fact affecting CPU usage?

 * I understand your eagerness to find an answer… but posting on every 4-5-6 months
   old, related topic the same isuee – is not helpful.
