Title: WordPress using high CPU Usage Last modified: August 22, 2016 --- # WordPress using high CPU Usage * [T4kuyax](https://wordpress.org/support/users/t4kuyax/) * (@t4kuyax) * [11 years, 9 months ago](https://wordpress.org/support/topic/wordpress-using-high-cpu-usage/) * Hello, * I have a problem with WordPress and Server and it is driving me crazy, **hope some experts like you cal help me 🙂**. * I was on a Shared Hosting and one night (Like 5 days ago) the server started to use CPU 80%+ and it make server go down. The sites I have on that server are new (No more than 250 total visitors per day) so the Hosting Company (**BanaHosting. com**) told me it was because a lot of PHP process was running. * I decided to move everything to **A Small Orange** (Cloud VPS) and it was OK but just yesterday it started again. * Its important to mention that all of that sites have a lot of backlinks (50K+) so a lot of bots come to comment (50+ spam comments everyday) so this maybe is the problem cause (I am not sure). * Its very strange, also its important to mention that I only use the following plugins on the websites: * **WordPress SEO by Yoast Akismet Contact Form 7 Jetpack by WordPress Pretty Link Lite Useful Banner Manager * Sites are using Genesis Framework Themes, so theme must not be a problem. * This problem is driving me crazy, one of the sites is currently off because if I turn it on in less than 2 minutes, it makes the VPS crash (Other sites use a lot of CPU too, 25%-50%) * **Do any of you have any ideas about this?** Its very very strange, also I have a friend with the same VPS and similar sites and they work perfectly. * **Thank you very much to all 🙂** Viewing 10 replies - 16 through 25 (of 25 total) [←](https://wordpress.org/support/topic/wordpress-using-high-cpu-usage/?output_format=md) [1](https://wordpress.org/support/topic/wordpress-using-high-cpu-usage/?output_format=md) 2 * Thread Starter [T4kuyax](https://wordpress.org/support/users/t4kuyax/) * (@t4kuyax) * [11 years, 9 months ago](https://wordpress.org/support/topic/wordpress-using-high-cpu-usage/page/2/#post-5181961) * No, it wasnt that plugin. * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [11 years, 9 months ago](https://wordpress.org/support/topic/wordpress-using-high-cpu-usage/page/2/#post-5181979) * Just some thoughts to put us all on the right track: * 1. How did you find out it was that plugin? * 2. How did you determine it actually wasn’t the plugin? * 3. How are things since you locked down xmlrpc.php as mentioned above, as well as the comments and login via .htaccess? * Thread Starter [T4kuyax](https://wordpress.org/support/users/t4kuyax/) * (@t4kuyax) * [11 years, 9 months ago](https://wordpress.org/support/topic/wordpress-using-high-cpu-usage/page/2/#post-5181982) * > Just some thoughts to put us all on the right track: > 1.

No cpu load. If you rename xmlrpc.php, you will force wordpress to spit out the 404 page each time. the “permission denied” error caused by revoking permissions is much faster. * [f.n174](https://wordpress.org/support/users/fn174/) * (@fn174) * [11 years, 6 months ago](https://wordpress.org/support/topic/wordpress-using-high-cpu-usage/page/2/#post-5182238) * i have same problem in my multisite . some times when i use wordpress import the hosting cpu gets up to 66 % and if i use that again it goes to 100%. for resolving that i see when i rename wp-admin cpu comes back to its normal. maybe it helps you too. * [enquirer32](https://wordpress.org/support/users/enquirer32/) * (@enquirer32) * [11 years, 3 months ago](https://wordpress.org/support/topic/wordpress-using-high-cpu-usage/page/2/#post-5182243) * I also have this problem. It has been written about extensively in other bbs without a specific solution. Wp developers dont seem interested. If you are having this problem please post here. It seems to effect the wp-admin. * [Volunteer Nimda](https://wordpress.org/support/users/volunteer-nimda/) * (@volunteer-nimda) * [11 years, 2 months ago](https://wordpress.org/support/topic/wordpress-using-high-cpu-usage/page/2/#post-5182245) * Yes, I think this is the problem I am having. * Have a wordpress multisite that has been installed and running okay of about 12-18 months. * Now my web host is constantly disabling the site as they say it keeps exceeding the resources allocated to me. * Web host not very helpful as they wont tell me what my CPU usage limit is other than 100%. * But have posted about it here https://wordpress.org/support/topic/is-jetpack- resource-heavy and here [https://wordpress.org/support/topic/is-a-multisite-resource-heavy](https://wordpress.org/support/topic/is-a-multisite-resource-heavy). * Would definitely like wordpress to investigate further. Dont want to have to redesign and reinstall web site as a single blog, but the suggestion currently is that each site within the multisite is one database and in effect I have 5/ 6 databased running at one time. * Supercache has been suggested but on that forum a user has point out it has crashed his blog on a shared host for exceeing CPU usage.
