I had posted question yesterday. That post can be seen at http://www.lkml.org/archive/2003/1/25/4/index.html After doing some more testing with standalone UDP program, the transfer rates are normal and as expected on 2.4.20. The same performance can be seen on 2.4.19. There is a similar posting at: http://www.uwsg.iu.edu/hypermail/linux/kernel/0210.0/1116.html --- Re: linux-2.4.20-pre8-ac3: NFS performance regression --- From: Alan Cox (alan@lxorguk.ukuu.org.uk) --- Date: Thu Oct 03 2002 - 17:13:04 EST --- In reply to: Andreas Pfaller: "linux-2.4.20-pre8-ac3: --- NFS performance regression" --- On Thu, 2002-10-03 at 19:32, Andreas Pfaller wrote: --- > However I noticed a significant NFS performance drop with --- > 2.4.20-pre8-ac3.

Hope this helps whoever is testing or working on related areas. Best regards, -Arun.
