Sites Slow after PHP Upgrade

[parkerj]

I upgraded my server last night to PHP 5.2.4 and then my sites were slow as molasses. So then I updated my server to version 5.2.13, and it was back to normal for a while and now it is still slow as molasses. Can anyone help me to resolve the issue? My site is at http://mulyoo.com.

Thanks.

Are there any errors in Apache's error log?
