Just for more clarification, here is a perfect example: 2.6.7-p1: 24.86user 51.77system 2:58.87elapsed 42%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (13major+7591686minor)pagefaults 0swaps 2.4.21: 28.68user 34.98system 1:12.34elapsed 87%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (5691267major+1130523minor)pagefaults 0swaps Both runs on the same machine with the same process (making headers). Could someone give me some pointers/directions on where to look. Thank you for your time.
