Really annoying, because it doesn't seem to add up the CPU time used by threads. Sometimes your CPU will be pegged at 100% and your system will be chugging, but 'top' doesn't show anything using CPU time because its some random subthread. I can never remember what the arcane option to turn on thread listing is for 'top'. That, and the move to NPTL, in I believe RH9, completely changed the way threads are done. This affected Java in particular. -------------- next part -------------- A non-text attachment was scrubbed...
