With -B 256 -F I'm getting around 70 tps, and I haven't got wonderful hardware: dual 450Mhz PII, 40GB SCSI drive, 320MB RAM, RH Linux 7.0.  I presume that these benchmarks are not adjusted statistically to compensate for hardware or anything like that.

pgbench -t 100 -c 5

With

pgbench -t 100 -c 10

I'm getting up to 85 tps, same server settings as above.

Has anyone run pgbench with the latest beta?
I'm seeing ~50 tps with 7.1b4 versus ~100 tps with v7.02 & 7.03 running postgres on FreeBSD v4.0.  I'm vacuuming before and after each test run and using -F with postmaster.  Originally I thought I had a debug build but what I'm seeing are debug msgs from vacuum.  JDBC interface is much slower...

Thanks.
