performance much improved

performance much improved

[William Lee Irwin III]

Earlier in the 2.4.x series I noted a strange anomaly:

NetBSD nfsroot clients were able to drive up the load on a 2.4.x NFS
server to 10 or 20. This was doubly surprising as the clients were
machines of far lesser power than the NFS server (e.g. sun3/60 vs. a
600MHz Athlon running Linux ~2.4.8).

A pleasant surprise occurred today while doing make build simultaneously
on all 3 of my NetBSD toasters (sun3/60, ss1, and decstation 5000/200):

The load average on my main machine (the NFS server, 2.4.18-pre7-ac3)
remained quite low, and the machine quite responsive.

I confess I haven't been following the developments closely, but I can
say thank you, and congratulations on the performance improvement.


Cheers,
Bill

NFS Utils package

[Tom McNeal]

Hi -

I've exported an NFS Utils package based on the latest checkins
on the CVS tree, which H.J. tagged as nfs-utils-1-0-1-pre3.  I
have tested it with 2.2, 2.4, and Solaris 7 servers, running with
a 2.4.18 client, running all 4 Connectathon 2002 tests simultaneously,
along with bonnie++ and a duplicate request cache test I developed
last year.  I set them up to run 20 times each, so there is a
constant mix of various tests doing different things for a few
hours in each test sequence. 

You can download the package from sourceforge:

http://nfs.sourceforge.net/nfs-utils-1-0-1-pre3.tar.gz

The notes for all the modifications are in the ChangeLog file
in the package.  The one that is of most importance to me is
the modification of the default behavior for nfs exports; The
default is now "sync", and you will get a warning if you don't
specify either "sync" or "async".

I will be out of town for a week or so, and won't be able to 
read the mailing list much at all, but I'll be reviewing status
later on next week, so go ahead and post comments to the mailing
list, and send any private mail directly to me at this address.

Regards -

Tom McNeal

Are your tests able for download somewhere ?
Do you know another nfs tests ?

Thank you, Tom.

And what about nfs-utils 1.0 ? It was mentioned here a couple of
month ago, but can't find it on sourceforge nfs page.

Re: NFS Utils package

[trmcneal]

The connectathon tests can be downloaded from
http://www.connectathon.org/nfstests.html
and the bonnie++ load I added came from
http://www.coker.com.au/bonnie++

I'm intending to rerun cthon02 with iozone as the
background load, when I am home again next week.  That
can be found at http://www.iozone.org, and I put some
instructions for running it in the performance section
of the NFS howto.

I won't have access to my duplicate request cache test
until next week, but connectathon does cover that.  One
thing to look for with 2.2 systems that don't support
large file sizes (> 2 gb) is that the special tests will
fail, but you can comment out the last test of the
special test sequence ("bigfile") to avoid that, if you
want.
