I have strange situation. I`m testing performance of PostgreSQL database

I don't know about 40-60% faster, but JFS is known to be a fast, good
file system -- faster than other file systems for some things, slower
for others. It's particularly known for putting a somewhat lower load
on the CPU than most other journaling file systems.
Alexander.
I was just reading some informations on the web (for example:
http://www.nabble.com/a-comparison-of-ext3,-jfs,-and-xfs-on-hardware-raid-t144738.html).
My test should tell mi if it`s true, but now I see that rather everyhing
is ok with my test method and the gain of using JFS is not so high.
