Rocco,
I published some stuff which is on Jan Depner's site. You can find
that in Google.
I used reiserfs on my audio partition with good success. If it's not
working well for you, then we should try and get to the bottom of why.
Do a few measurements.
Wizard root # hdparm -tT /dev/hda
/dev/hda:
Timing buffer-cache reads: 768 MB in 2.00 seconds = 384.00 MB/sec
Timing buffered disk reads: 130 MB in 3.01 seconds = 43.19 MB/sec
Wizard root #
The first speed is talking only to the drive's buffer RAM, so it's very
fast. The second is actually reading off the drive, so it's more
important.
What sort of numbers do you get?
Remember, rotational speed is only one of the aspects of how fast a
drive is.
Good luck,
Mark
