nfs speedup in current compared to 5.2 RC2

[Claus Guttesen]

Hi.

Was testing 5.2 RC2 as NFS-server. Mounted three
NFS-clients (two 5.2 based on i386-port and one
current as of Feb. 13'th based on amd64). I mounted
with tcp ver. 3 and r/w data size set to 16384.

Then I started copying 4-5 GB back and forth. In RC2 I
would occassionally get a 'NFS-server stopped
responding/NFS-server alive again' on the client.
Meanwhile I did a http-upload from a browser which did
not complete.

I cvsup'ed to current as of Feb. 18'th approx. 13.00
GMT and upgraded the server. Did the same test as
mentioned above, this time the NFS-server kept
answering during the copying.

So I mounted all my six web-servers (NFS-clients)
which is a mix of 5.1->5.2 (i386), one test-server
(amd64) and one RedHat Linux and started another copy.
Albeit slowly the copying did complete without any
errors.

My http-upload was also succeeded.

Although this only applies to my particular
environment I have the impression that NFS behaves
better in current compared to RC2.

Hardware is Compaq DL380 dual Pentium III, qlogic 2300
FC, approx. 1.5 GB RAM, GB em-NIC.

regards
Claus
