Does anyone know the option I would have to enable in the config when
building the kernel?
Also is there a enough performance gain to warrant recompiling the kernel?
Thanks for you help
Randy

Yes, but you need to recompile the kernel to get support for it.

Well it depends on how clean your networks is. If you're getting a bunch
of retransmits
using UDP, then TCP should smooth things out (since TCP is much better
at dealing
with retransmits that RPC over UDP), but if the traffic is already
pretty smooth, then
performance may decrease a very small amount due to the TCP overhead.....
But the gains of using a smarter transport (i.e. TCP) outweighs the very
small performance hit... imho...

Thanks for the response
What is "FC1"
I am connect between two boxes with a crossover and gigabit nic cards
I a, trying to figure out ways to get rid of this error message on my
console about a host not responding.
I was thinking maybe tcp would help

Hello
I have two rh9 boxes. One is the NFS server and one is the client.
They are very busy web servers that share the same document root via nfs.
i keep getting these errors on my console and in my message file May 3
12:44:11 krusty kernel: nfs: server local.flanders not responding, still
trying May 3 12:44:15 krusty kernel: nfs: server local.flanders OK
these two boxes each have a GIGaBit ethernet card and a crossover cable
connecting each other and it is only used for NFS.
All other network functions use the other nics
Stats are below, I am currently running 49 nfsd's
Thanks for any suggestions
