Yeah, the problem doesn't appear to be there. As I said, if I look at the PS of the system when its bogging, there aren't a whole bunch of processes stuck doing these, so while this does take a second or two to come back, that's not that bad. Its GENERAL performance that just bites - the system is obviously out of CPU, but what I can't get a handle on is WHY. It does not appear to be accumulating large amounts of runtime in processes I can catch, but the load average is quite high.
8.2.3 has the 'stats collector bug' (fixed in 8.2.4) which increased load in high concurrency conditions. on a client's machine after patching the postmaster load drop from the 4-5 range to 1-2 range on a 500 tps server. maybe this is biting you? symptoms are high load avg and high cpu usage of stats collector process. merlin ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
