i can't replicate this. i get 1.12MB/s sexyz to sexyz (syncterm) with zmodem and 0.86MB/s with ymodem-g sexyz to sexyz. certainly an improvement over mystic's but something is a bottleneck.

this is on an i7-3520M .. no spring chicken for sure. both transfers used 38-50% cpu during the transfer. (for comparison a 65MB/s transfer to the same machine uses 8%)

i can totally see gkermit outperforming ymodem-g.
