I meant to try a transfer with the source machine and another one beside my main rig....but the other night the transfer queued and went quickly. That is, I calculated, near 100mbit. So I guess my onboard Enet is 10/100.
Right now, it's being a pig again. Seems there's something weird with this computer, as I did try my old router and it was just as bad.
Consider it high comedy....sincere tragedy....whatever...don't take it personally.
