Are the TPS numbers per pgbench? If so, then you're getting 10x490=4900 TPS system wide, or 20*280=5600 TPS system wide. If those are total TPS numbers then you should check your disk utilization and CPU utilization and see where your bottleneck is. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
