Support » Fixing WordPress » CPU overload

  • I have several WordPress on my server, some mine, some of my clients.
    I have seen that in the Daily Process Log, they are returning

    Top Process %CPU 120 /usr/bin/php /home/xxxxx/public_html/index.php
    Top Process %CPU 101 /usr/bin/php /home/xxxxx/public_html/index.php
    Top Process %CPU 88 /usr/bin/php /home/xxxxx/public_html/index.php
    Top Process %CPU 65 /usr/bin/php /home/xxxxx/public_html/index.php

    I have asked them to deactivate all of their plugins, but the problem seem no to be there in the plugins.

    Is is WordPress issue, is it server issue? If it is server issue, what should I change in the configuration?

    A phpinfo you can find here.

  • Yes I am way over my CPU limit at 124% which just started mysteriously with no new plugins installed. I have tried both wp-super-cache & hypercache with db-cache-reloaded, to no affect. I have really wasted lots of time with no answers.

    my blog is also down. CPU overload problem. No traffic of data but server collapsed. last wordpress version 2.9.1. installed

    Anyone has any idea?
    I understand from this issues, that is not a server configuration, but a wordpress issue.

    My Host just closed my account for CPU usage!
    i signed with justhost one month ago for a forex website (no trading)just information and education with post website, i already have 4 or 5 pages! after they suspended my account within few hours i got this email

    For your reference, here is a copy of your usage report:

    Now my question how this happen? this is new website
    ! few pages, about 4 flash ads and adsense with couple of amazon books!
    i am using wordpress and i was trying plugins but i also tried to download SiteBuilder Elite through fileZilla!
    i just started out this website business and i hardly made $6.20 for the month of February with those few pages!
    please can someone advise me on what to do?
    i did sign with inmotion for business account and i was told if this CPU is high then i need private server which cost lots of money!! i don’t know how people with 200 sites do it! Any advise please?

    Please can someone tell me how do you know your CPU limits and how do you find out how much are you using?


    I have a problem similar to this one. The situation is as follows:
    – brand new WordPress install with wordpress 2.9.1
    – installed/activated a few plugins ( 2, 3 – no more )
    – added a few posts, less than 20
    – in meantime wordpress got updated and I updated the install to 2.9.2
    – IMPORTANT: the site is on a new domain, therefore there was absolutely no traffic, but myself accessing the site
    – the conclusion is that somehow wordpress used all the server CPU and the account had to be suspended

    also note, that the server logs stated the strange activity with the /wp-content/themes/index.php file, file which is EMPTY! – there was some strange recursion taking place, the script was recalling itself and this alone generated over 2 Gb of traffic for the hosting account in a couple of days!

    Is there any way to figure it out what the problem is?

    Thanks in advance,

    All I can say is, me, too! I have two WP sites on this one server account, and they are constructed almost identically. One is experiencing the overload, and one is not.

    Evidently there is no knowledgeable person on here who can help us!


    i had the same problems too

    SInce WordPress is a dynamic blogging platform, it is possible for one blog to use more CPU resources than another identical blog, especially when one blog has far more traffic than the other. As a dynamic blogging platform, WordPress generates the page each time it is viewed. Since it is not pulling the data from a cache, this requires some CPU resources to run the necessary database queries to display the posts. Though these queries use very little CPU on their own, add in a few plugins and a few thousand visitors every few minutes, and you may start to see some problems.

    This is nuts. I see lots of threads throughout the internet with people complaining about the same thing but no solutions to be found anywhere. Like others, my cpu started to spike for no reason. I dropped all but a few essential plugins and I’m on 2.9.2 and no help. Changed from WP Supercache to W3 Total Cache and still nothing. My cpu goes between 5% to 12% when it needs to be at 1%. I only have about 800 pageviews a day.

    Luckily, my host Lunarpages have been patient in helping me troubleshoot this problem but all they can tell me is index.php is using too much load which is basically useless. They have already shut me down once so I’m walking a tightrope.

    My last resort is to reinstall the blog in another folder but no guarantees that will work.

    Did you fix the problem? The same issue is affecting two of my blogs too!

    No resolution yet. I have tried everything. Part of the problem is that I’m running two blogs on my host and the cpu report is a summary for all activity so it’s hard to isolate. If I bring it down to just one site running bare, it’s still at about 2-3% when they want it at 1%.

    My last option is to install a new blog in another folder and move my content to the new blog to see if that helps. I don’t think it will as it is starting to look like wp is just cpu hungry. I only get 800 pageviews per day with about 500 visitors. I hate to see what would happen it it gets more popular.



    Well it seems there are very few solutions to these high cpu problems so I wrote my own tutorial on how to tame cpu usage. Hopefully, it’ll help someone.
