NFS copies from a Fedora 8 server using a National Semiconductor
PCI gigabit card are extremely slow, with a a short burst of ethernet
traffic every 20 seconds or so. An 800 MB disk image took 708
seconds to transfer over the gigabit local network. A concurrent
VNC connection times out during this file copy. Other clients
accessing the internet through NAT on the server were similarly
disrupted during the NFS file copies.
An FTP transfer between the same two systems was about 20
times faster, without disrupting a VNC session.
Server: Fedora 8 x86_64 AMD 6000+ dual core ECS Nforce6M-A
motherboard, National Semiconductor PCS gigabit ethernet card.
Client: Intel Cure Duo on Intel DG33BU motherboard, onboard
ethernet.
Workaround: Reconfigure server to use motherboard ethernet
for local network, PCI card for cable modem.
