3.1.7? A major scalability bottleneck caused by spinlock contention was fixed in 9.2 - see commit b4fbe392f8ff6ff1a66b488eb7197eef9e1770a4. I'm not sure that it's very meaningful to do performance testing on versions that are known to be out of date. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
