Same as we discovered a few years ago.

Here are some numbers:

especially numbers from jade.e.kth.se are intressting for you.

These were the tests i made with afsfsperf before we started to our
AFS-Cell from Digital UNIX to Linux. We decided to go with reiserfs and had
no known problems related to the filsystemtype ever.

I do recommend reiserfs for /vicep* .
