I have some more results now.... 8 socket machine 10 min run(median of 3 run) synchronous_commit=off scal factor = 300 share buffer= 8GB test1: Simple update(pgbench) Clients Head GroupLock 32 45702 45402 64 46974 51627 128 35056 55362 test2: TPCB (pgbench) Clients Head GroupLock 32 27969 27765 64 33140 34786 128 21555 38848 Summary: -------------- At 32 clients no gain, I think at this workload Clog Lock is not a problem. At 64 Clients we can see ~10% gain with simple update and ~5% with TPCB. At 128 Clients we can see > 50% gain. Currently I have tested with synchronous commit=off, later I can try with on. I can also test at 80 client, I think we will see some significant gain at this client count also, but as of now I haven't yet tested. With above results, what we think ? should we continue our testing ? -- Regards, Dilip Kumar EnterpriseDB: http://www.enterprisedb.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
