    As mentioned, run top and see what's using the most resources. If it's MySQL, you may want to install the WPCache plugin.

    More specifically, this allows easier copying of the data:

    Start by installing the WordPress Hyper Cache plugin.

    Loadavg does not necessarily mean increased CPU usage. Run top or get "htop" (My personal favourite) and have a look at what is using your CPU or what else you have running.

    Just PHP. You get lots of hits to your website?

    Maybe you should cut down on the number of PHP processes.

    I'd suggest switching to FCGI or DSO and installing solid Caching on the script.

    i have WP Super Cache install already is Hyper Cache better or different? should i have both?

    You should only have 1 caching plugin at a time. There's no harm in trying a different one, but disable WP Super Cache first.

    There's a chance that the cache mechanism has broken somehow, which would account for a sudden high load. Do you have any way to check whether it's working correctly?

    It kinda looks like you're reaching the limit of your hard disk for streaming with the iowait. It doesn't help matters that your supercache is dropping back down to php/mysql. Try to enable the mod_rewrite support in WP Super Cache.

    I would second this.

    The way you have php set up (suexec/suphp as a cgi) is the most inefficient way to do it.

    It could possibly be those plugins are having an adverse effect, could you switc off the plugins one by one to see if the problem goes away?
