Perhaps it depends on your definition of "fast". NFS slowness is my
albatross. Most of our work is IO bound now.. and a dozen or so fast
multi-core Linux workstations all pounding on a Linux NFS server doesn't
NFSv4 should be better, but in Fedora my users occasionally get lots of
"kernel: BUG: soft lockup - CPU#1 stuck for 61s!" for a process that's
"stuck" (aka uninterruptible sleep) in NFSv4 land.
