Just to refute that... I get almost 2Mb/s over lo0 with ssh. This is
with standard compression/decompression and idea encryption/decryption.
Since this has to run both ends, my K6-2 350 is really doing 4Mb/s or
higher (take into account lo0 overhead.) I'd expect a P6 (II, whatever)
running at at 450 to beat that, by around 15%.
