shared_buffers (156M) looks in line with various tuning guides' recommendations given 2G of RAM; effective_cache_size (538M) might (or might not) be low, depending on how much memory other processes are using up. Tuning guides like the one I mentioned and the folks in pgsql-performance should be able to help determine good values to use. -- Michael Fuhr http://www.fuhr.org/~mfuhr/ ---------------------------(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
