Uhm, yeah. I suppose...

I suggest downloading the tarball of the mandrake 2.4.8 kernel which has 
XFS support.
http://iserv.nl/files/xfs/ It will probably do a lot better.
It is 38% faster with ext2 then the 2.4.2 kernel that came with redhat 7.1

I let the box run with continous IO from mongo.pl with 50 processes which 
produced a constant load average of about 52. The box was sluggish but had 
a good response. It run for a day without crashing.
This was with ext2, xfs tomorrow.

Uhm there are no XFS patches for these (lack of time) and since the VM 
between -ac and -linus differ so much it can not sanely be applied.

The mandrake people did have time for creating a -ac kernel with XFS which 
is why I recommend that kernel from now on. It is similar to the redhat 
kernels that are on installer CDs.

SuSE includes patches as well in their kernel but I don't know if they base 
it on -ac as well?
