I have 3 HUGE NFS servers (Each one with 2 -3 terabytes = each), and 10 clients that pull a consistent 20-25 MBit total off of the 3 NFS servers. Everything is running fine, but performance isn't = the greatest... I can never pull more than 1 Megabyte per second off of = any of the servers (Even though local performance of drives on the = servers is GREAT)... My question is this? How would switching = everything to gigabit copper instead of 100 MBit lines help. Obviously = Gig is faster, but since I am not even using the 100 MBit I am = wondering? The latency should go down because it transfers so much = faster? Any ideas for me? Anyone do this themselves that can answer?
