RHEL 5.0 NFS

[Matt Brown (Sky Road LLC)]

I would still take a look at that document if it is performance related.
Don't just toss it because it says Oracle in there, I would check the TCP settings and the kernel scheduler that is all in that document.
We tested against two system one with Red Hat 4.6 the other 5.5 and the 4.6 machine was beating the 5.5 machine by 50% before we started making changes to the kernel settings. I am just saying it might not be NFS it might be kernel related.

I don't understand how nfsv4 is causing problems. If it's not being used
by the clients then it serves no function. If the clients are trying v4
support you can force nfs v3 or even v2 as a mount option.

What problelm do you think nfsv4 is causing?
