I ran pgbench with a scale factor of 1000 and a total of 100,000
transactions per run. I varied the number of clients between 10 and
100. It appears from my test JFS is much faster than both ext3 and XFS
for this workload. JFS and XFS were made with the mkfs defaults. ext3
was made with -T l

I'm curious as to what this means - did they have problems integrating
it into their toolchain or are there actual problems going on in jfs
currently?
I've found jfs to be the least stable linux filesystem and won't allow
it anywhere

Did you seperate the data & the transaction log? I've noticed less than
optimal performance on xfs if the transaction log is on the xfs data
partition, and it's silly to put the xlog on a journaled filesystem
anyway. Try putting xlog on an ext2 for all the tests.
