I actually ran the test on my laptop. It has an Ultra ATA/100 drive (5400 rpm). The test was just a quickie to show some data from the probes. I'll collect and share data from the T2000 server later.Hmmm ... AFAICS this must mean that flushing the WAL data to disk at transaction commit time takes (most of) 20 msec on your hardware. Which still seems high --- on most modern disks that'd be at least two disk revolutions, maybe more. What's the disk hardware you're testing on, particularly its RPM spec?
