Sorry if you already answer this question, but at least I can find it in 
the thread.
What scheduler are you using on RELENG_7 ?
Did you check with both schedulers (ule/4bsd) to see which one works 
better for you?
Also are you sure that you service the same number of requests - I see 
that the 6.x image shows CPU usage from
Aug 2007 and 7.x image is from Jan 2008 ...  is it possible, that you 
have more requests and that's why your CPU usage increased?
