Subject [users@httpd] Apache waiting for i/o -> optimizing
Date Tue, 18 Sep 2007 17:52:28 GMT

The delivery of my sites is getting somewhat sluggish, so I checked top 
and it say that 30% of my CPU time is just waiting for i/o.
Is there anything that I can do about this, as in optimizing Apache?
I'm thinking about caching mechnisms, but I have now over 6.000 sites 
running, so I'm not expecting caching to be useful. Am I wrong on this?

Since getting an addional server is not possible right now, is there any 
way to ease the situation?
