Downtime due to WordPress 2.5 high CPU usage

Sorry for the downtime guys. I have reached my CPU usage limit due to turning on automatic database backup feature in WordPress (or something else – not quite sure).

Lets hope from now on everything will be ok.


With my blog suspended for second time I got really pissed and investigated the reasons. My previous believes about buggy pluggins was not correct and with little googling I found out that WordPress 2.5.x has some serious problem with CPU usage. As I examined my load logs it is obvious that the PHP process is using more than 5 times as previous versions.

The solution is either to install WP Super Cache or to downgrade to the previous version before 2.5.
