okay this plugin I use called dsidxpress is leaving some entries in my wp_options when I read mysql-slow.log ... I sent a query to the developer's support team and they have not gotten back to me.

I upgraded my linode to a 768 and everything seems to be running excellent in terms of cpu/memory.. I think that is actually overkill for the amount of traffic I get but since I have 450 MB allowable to mysql it keeps some free memory when mysql does get worked hard? Is this a bad way to look at it?

BUMP - at since my last post and upgrade to a Linode 768 I have not experienced any more IO spikes but my CPU has been running too high numerous times, however it comes back to normal and corrects itself after a huge spike, can anyone help me diagnose & cure this one? Chesty? Nuvini?

I've actually had this problem for a while but haven't done anything about it since it wasn't crashing my server it wasn't a top priority
