Title: 100% CPU Load Last modified: August 18, 2016 --- # 100% CPU Load * [infocynic](https://wordpress.org/support/users/infocynic/) * (@infocynic) * [20 years, 1 month ago](https://wordpress.org/support/topic/100-cpu-load/) * OK, I have tried everything I can think of… (list below) serving any WordPress page spikes my CPU up to 100%. * Current Specs (see notes below): Athlon XP 3200 Win XP Apache 2.2 PHP4 MySQL 5 Wordpress 2.0.2 * Have tried: Apache 1.3, 2.0 PHP5 Various Apache directives like Win32DisableAcceptEx, EnableSendfile Off, EnableMMAP off Disabling all WordPress Plugins Disabling the “compress … if browsers ask” option * A small test page I made that directly communicates with the same DB server ( albeit on a smaller scale) loads OK, spikes to maybe 60-70% CPU … * The pages load, they’re just a little slow (even on localhost), and the CPU hit is killing me when I’m trying to do other things (e.g., watch videos).

Looking at the list, I don’t see anything else I was using currently… I have more than that installed, but everything’s inactive. * [abhideydas](https://wordpress.org/support/users/abhideydas/) * (@abhideydas) * [20 years, 1 month ago](https://wordpress.org/support/topic/100-cpu-load/#post-364360) * can you please post what programs, antivirus, firewall, etc are running. * Thread Starter [infocynic](https://wordpress.org/support/users/infocynic/) * (@infocynic) * [20 years, 1 month ago](https://wordpress.org/support/topic/100-cpu-load/#post-364424) * Firewall: ZoneAlarm (free) AV: Symantec Corporate 10 * Others: PeerGuardian 2 SharpReader (for RSS) Thunderbird GMail Notifier Motheboard Monitor 5 AIM Triton mIRC * Most everything else is temporary… iTunes or Firefox could easily be open at any time… but nothing else runs full-time. * [abhideydas](https://wordpress.org/support/users/abhideydas/) * (@abhideydas) * [20 years, 1 month ago](https://wordpress.org/support/topic/100-cpu-load/#post-364426) * right, usually AV’s and firewalls turn out to be resource hogs. can you please see your resource monitor and see which processes are taking the most of CPU power when it spikes to 100%. * you can find it under ‘process’ tab after hitting ctrl+alt+del. * Thread Starter [infocynic](https://wordpress.org/support/users/infocynic/) * (@infocynic) * [20 years, 1 month ago](https://wordpress.org/support/topic/100-cpu-load/#post-364435) * httpd.exe (the unofficial apache 2.2 build I’m using, but remember, this same thing happens with apache.exe if I use official 1.3 or 2.0 builds), and then firefox makes a quick spike as well. HTTPD will be using 50-70% of the CPU or even as high as 90 in some cases, and FF will be using up to another 30-35 or so. * [abhideydas](https://wordpress.org/support/users/abhideydas/) * (@abhideydas) * [20 years, 1 month ago](https://wordpress.org/support/topic/100-cpu-load/#post-364515) * i believe it is due to a [bug](http://archive.apache.org/gnats/6816) in apache. you may try upgrading to the latest version and see what happens. * Thread Starter [infocynic](https://wordpress.org/support/users/infocynic/) * (@infocynic) * [20 years, 1 month ago](https://wordpress.org/support/topic/100-cpu-load/#post-364524) * I tried 1.3.34, 2.0.55, and 2.2.0.
