That sounds more like it. Even copying each individual byte from one buffer
to another shouldn't take any significant amount of time at 2Mbytes/sec
(which is about the amount of transfers that were taking place).
Since you've seen much different results, I guess I should investigate a
bit more, see if I can figure out exactly what's causing the difference
(I'll try a few other networky operations, and I've got a PCI card Realtek
in my stack of spare parts somewhere too.)
