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 <hostname> dump | dd <reblock it out to tape>" was faster. I confirmed that result going to a disk buffer. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
