Keep in mind that drives have a faster data transfer rate at the
outer-edge than they do at the inner edge, so if you've got

To test I use pgBench with default database schema, run for 25, 50, 75
users at one time. Every test I run 5 time to take average.
Unfortunetly my result shows that ext is fastest, ext3 and jfs are very
simillar. I can understand that ext2 without jurnaling is faster

I have strange situation. I`m testing performance of PostgreSQL database
at different filesystems (ext2,ex3,jfs) and I cant say that JFS is as
much faster as it is said.
I don't know about 40-60% faster, but

You were doing your tests with a database scale of 50. As Heikki already
pointed out,
