I must admit I still haven't really understood it -- I know that it appears on multiple operating systems, on multiple architectures, but most with Xeon CPUs, and that it's probably related to the poor memory bandwidth between the CPUs, but that's about it. I've read the threads I could find on the list archives, but I've yet to see somebody pinpoint exactly what in PostgreSQL is causing this. Last time someone claimed this was bascially understood and "just a lot of work to fix", I asked for pointers to a more detailed analysis, but nobody answered. Care to explain? :-) /* Steinar */ -- Homepage: http://www.sesse.net/ ---------------------------(end of broadcast)--------------------------- TIP 3: 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
