Here's another run, with noatime on, and default postgres
parameters.

tuning? single ir mx-ir oltp mixed-oltp
(sec) (tps) (sec) (tps) (sec)
ext3 dn 1296.30 66.34 207.59 69.19 318.26
ext3-wb dn 1286.38 66.27 212.48 135.48 229.74
ext3-jd dn 1293.08 68.72 209.33 113.40 283.97

Looks like I'll have to invest some time in tuning postgres
a little better before the filesystem becomes more of a
bottleneck.
