What can I expect for Gigabit NFS performance between my F630 NetApps and a pretty hefty Linux box, both running Gigabit network devices? ....
The best I've been able to do on a Linux box (Red Hat kernel) with an e1000 interface is 16-17Mbps. Here's a test nearly identical to yours; the remote file lives on an F820 running 6.1.3:
[cfst]$ ls -l cse509.tar.gz -rw-r--r-- 1 root wheel 299598195 Aug 9 2001 cse509.tar.gz
[cfst]$ time cp cse509.tar.gz /dev/null
real 0m17.126s user 0m0.029s sys 0m1.652s
[cfst]$ perl -e 'printf "%.2f\n", ((299598195/17.12)/(1024**2))' 16.69
That's about the same total bandwidth I saw *outbound* from the same Linux box (which is an nfs/smb server) when I had a bunch of nfs clients doing simultaneous reads.
