I often sync big files (between 300 and 700/800 MB) between two
machines, and the transfers seems to be at least beyond 4-5 MB/s, using
NFS and FC1 on both.
I detect only disimilar rates depending the machine which mounts nfs.
One machine is a laptop with Pentium-III and a ATA66 harddisk, and
another a desktop with Athlon XP 2.0 and ATA133. Seems that the 66 MHz
IDE bus limits the transfers when the laptop mounts and receives the
data. Anyway, beyond 4 MB per second, I sync files of 800 MB in less
than six minutes, sure. (Done a few minutes ago....:-)
There are not special hardware....a PCMCIA 10/100 Ethernet, another one
built in motherboard, and a ADSL modem router (which works as switch
between machines, apart from supplying Internet access), often working,
even when I transfer the files. Nothing seems to smell burned...:-)
If some process drain CPU power, then the transfers rate falls
dramatically, below 2 MB/s. By example, if I'm seeing that videos with
xine...but that's I like Linux......do not try to do it under
anothers......without a blue sun glares, I meant.....:-)
