My machine is an Athlon/1200MHz
My other machine is a Duron/600MHz
Both use a cheap rtl8139 based NIC

FTP get a CD image:
	733902848 bytes received in 63.95 secs (11207.0 kB/s)
Then put it back:
	733902848 bytes sent in 73.62 secs (9734.5 kB/s)
Both machine used 35-45% cpu during the transfers.

No IP filtering active, but this process would take the same
amount of cpu regardless of the NIC, right?

Hope this gives some idea of what to expect.
