Thanks for the info. I don't think the tests really benefit from this much resources, I would be rather surprised if it was faster beyond 8 cores or so. The CPU frequency likely matters much more. Which probably explains why this machine was the slowest. Also, I wonder how much the results vary between the runs. I suppose you only did s single run for each, right? regards -- Tomas Vondra EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
