Subject: NFS & 2.4 VM Performance

We're looking into using Linux as a file server and
would like to know more about NFS performance
in general. If possible, we prefer 2.4.x kernel -
unfortunately, a discussion archived in "mlist.linux.kernel"
news group raises concerns:

http://www.ussg.iu.edu/hypermail/linux/kernel/0104.0/0598.html

It said that the 2.4 VM was lacking the ability to
efficiently manage page fragmentation that, in turns,
would cause few free buddied pages available for
NFS requests, etc. Since the discussion was held
long time ago (April 2001), I'm wondering whether
the newer versions of kernel (say 2.4.19) has any
fixes or patches to eliminate/alleviate the problems ?

Or should we just directly jump into 2.5.x kernel ?

Thank you for the helps.

Wendy
