I’m having the same issue with one of my sites. The CPU was jumping and crashing the site. We were getting 500 errors intermittently throughout the day.

I changed themes, got rid of all the plugins I could, turned on debug to see which plugins might be throwing errors. Some were, so nixed them and replaced them with good plugins.

CPU still spiked. Then my host said they thought it was from wp-cron.php running too many processes every minute. So I disabled wp-cron, and ran it manually twice a day. Got the CPU down from 13 to 2-3, but my host wants it around 1%!

I also installed WP Super Cache, which I like a lot. My site loads way faster and works great, but this doesn’t seem to bring down the CPU more.

This is really frustrating! Now I have a plugin called wp-cron so I can see what process WP’s plugins need from wp-cron.php from the dashboard, and I installed WP-Cron Control, which is supposed to prevent wp-cron from going nuts and running when I want it too, just twice a day.

Still the CPU spikes. But what’s really confusing is I have my personal site with 3 instances of WP from the same host, just as much traffic, more plugins, yet that CPU is always under one percent! I don’t get it!

Is it the host server set up? Or is WP just a memory pig? I don’t know.
