Subject: NFS Performance issues...

I run a fairly large free/paid hosting service. We have about 8 webservers (NFS Clients) that hook up to a single NFS server box. We
are having SEVERE performance issues. The clients are READ ONLY clients. We have set the rsize to 8192 bytes, but otherwise
are using the standard setup. The NFS server seems to be able to only serve about 11 Mbits of data before it dies? Is this typical
performace? We are mostly serving web pages so most files are small although some are bigger (3-5 megabytes). Both the clients
are the server are redhat 7.2 (NFS 3)

I AM LOOKING FOR SOME COMMERCIAL SUPPORT or some guru I can pay to help with these issues. PLEASE give me a call
at (801) 361-1177 if you would be able to help. We will pay for the support we need.

Thanks,
Matt Heaton

You fail to mention what kernel version you're running?

Sorry, we have a 100 Mbit Network. A cisco 2924 switch where everything =
is
plugged into. An ALTEON Load balancer/firewall. We are running 2.4.7-10
(Redhat 7.2). I believe it might be something with the kernel as somethi=
ng
the
memory just spirals down. Doesn't 7.2 have some virtual memory problem l=
ike
that?

First off all, try updating to the errata kernel, 2.4.9 (it's in the
updates-directory on evey redhat-mirror).
