This is pretty cool, particularly because it affects single-client performance. It seems like a lot of ideas people have had about speeding up pgbench performance - including me - have improved performance under concurrency at the cost of very slightly degrading single-client performance. It would be nice to claw some of that back. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
