The ftp from a host on a connected network is slow and bursty. >Did you test performance too? Yes, it was crap... About the same sort of performance as one would expect if there were a duplex mismatch, yet we would see the same performance where it was auto-auto, 100full-100full 100half-100half... Barely a Mb/s on a directly connected host off the switch. >If >so, how did you do that? What switch do you have?) Noticed first on a Bay Centillion 100 and repeated on a Baystack 350T. The units are scheduled to go back to the supplier as we swapped them out for a slightly more expensive MB with onboard fxps. I can dig one of them out if you want more information before I send it back. ---Mike
