I had a friend of mine (Robert, you know Jeremy) and results are slightly different from what Evginy found. The summary is: Batching always is better, jiffies is always the better clock source (and who would have thunk,eh? Opteron kicks a Xeons ass). Attached results. Evgeniy, did you sync on the batching case with the git tree? Can you describe your hardware in /proc/cpuinfo and /proc/interupts? cheers, jamal
