People often run much larger volumes than this on PostgreSQL, but generally not without using connection pooling. http://wiki.postgresql.org/wiki/Number_Of_Database_Connections Personally, I managed a machine which typically had 3000 users running queries against it while about 20 million INSERT/UPDATE/DELETE statements per day were run against it. Tuning showed best performance when we used connection pools with 35 connections for read-only queries and 6 connections for the DML. Expect to spend some time adjusting the configuration for your particular hardware and workload. -- Kevin Grittner EDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
