Hi all, I have a server with 4 x Intel(R) Xeon(R) CPU E5640 @ 2.67GHz and * 12 GB* of memory. * There will be hosted ~100 databases with lot of reads and some writing. My postgresql.conf is:* listen_addresses = '*' max_connections = 300 shared_buffers = 3072MB work_mem = 72MB maintenance_work_mem = 704MB synchronous_commit = off wal_buffers = 8MB checkpoint_segments = 16 checkpoint_completion_target = 0.9 effective_cache_size = 8GB default_statistics_target = 50 constraint_exclusion = on Is this good configuration?
