So you are running kernel version 2.4.9 on a debian (Sid) box?

That sounds very nice indeed ;-)

That was what i was planning to use. Woody seems to be pretty stable
these days and ive read that it has gone into freeze, which IMHO makes
it a good choice for productionenviroments that needs to be stable but
still fairly new regarding features.

We are not. Currently we have a NetBSD box as our gateway but thats it.

I find it strange that ReiserFS has made it into the 2.4.x kernel not
being overall ready while XFS did not? Are there any history reason or
are they just a coincident?

Which is exactly those filesizes or even bigger we are heading
for. Are there any online performances test on read/write/delete for
XFS? CPU use etc.

Samba 2.2.1 on debian (Woody)? Or did you compile it yourself?

Do you have any stats for read/write for those systems?
