If you want comparable results, you simply need to count and breakdown kernel vs. user. Here how you can do this (assuming Core 2): pfmon -eunhalted_core_cycles,cpu_clk_unhalted:core_p,cpu_clk_unhalted_core_p --priv-levels=uk,u,k 2to3 You will get 3 counts out. The first counts user+kernel cycles, the 2nd only user, 3rd only kernel. ------------------------------------------------------------------------------ Stay on top of everything new and different, both inside and around Java (TM) technology - register by April 22, and save $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. 300 plus technical and hands-on sessions.
