Just out of curiosity, have you tried not using the rmt protocol, but using rsh (or ssh) to copy the data over? Some work done at stanford in the early nineties showed that rmt was *very* slow, and simply doing "rsh dump | dd " was faster. I confirmed that result going to a disk buffer. http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
