Been having interesting times with an IBM x3650 with 8 15k RPM 73GB drives in RAID 10 and a ServRAID 8K controller with Write-Back cache enabled (battery installed and working). Currently getting a pgbench score of 4.7 transactions per second!
pgbench is a very high level test of your system. It can tell you when a system is doing well, but it's almost useless for figuring out what's wrong if there's a problem.
You shouldn't run pgbench until you've first done a lower-level benchmark such as bonnie++ on the hardware. That should give you a better idea what's going on here, and if the badness shows up there it will be much easier to get someone at IBM to pay attention too.
