I have 7.1 and 7.3 clients. Haven't had many problems over the years and the recent 2.4 kernels are much improved. Currently I'm running the RedHat 2.4.20-20.7 kernel. I used UDP transport for a long time but have recently changed to TCP for nearly all my clients. > > As far as tuning goes, that gets rather extensive, from the MTU on up to the > NFS r/w sizes, as well as even the network topology.

This is for heavy r/w access. My usage is largely read. Performance has improved quite a bit as the kernel version has increased. I can get around 80% (ie. 80% wire speed) the throughput of a 'similar' Sun. Problem is that most of the Sparc clients can saturate 100Mb (onto a gigabit backbone) so I don't really know what the difference is.
