I suspect because of the nature of its workload, in my experience
pg_bench is lousy for measuring filesystem performance: it always
bottlenecks somewhere else.
Chris Browne did some work for us some time ago evaluating XFS, JFS,
and ext3, and concluded that JFS was the best under a high-update
load; that workload was selected precisely because it was I/O bound.
I thought he sent the results to the -performance list, but I can't
put my hands on the email right now. Chris?
