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? -- Best Wishes, Stefan Lambrev ICQ# 24134177
