Re: NFS/UDP/IP performance - 2.4.19 v/s 2.4.20, 2.4.20-pre3

Hello...

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.

So, the problem may be with NFS. NFS is not an issue for me 
and I can do with this problem. Hope this helps whoever is
testing or working on related areas.
