Hi, I would like to know if my configuration is ok, We run a web application with high transaction rate and the database machine on Mondays / Tuesdays is always at 100% CPU with no IO/Wait . the machine is a Dual Xeon Quad core, 12gb RAM, 4gb/s Fibre Channel on Netapp SAN, with pg_xlog on separate Lun, Could you please provide some feedback on the configuration
maintenance_work_mem = 704MB constraint_exclusion = on checkpoint_completion_target = 0.9 effective_cache_size = 8GB work_mem = 72MB wal_buffers = 8MB checkpoint_segments = 16 shared_buffers = 2816MB max_connections = 32 I have limited connections down to 32 as if I put up higher the machine load average goes through the roof and will decrease performance even more. In the process of looking at a 4 x AMD 6 core Opteron machine with 32GB Ram to replace if I cannot get any more performance out of this machine Kind Regards Christopher Dunn
