i calculate 1/0.080s/rt * 64*1024 = 819 kbytes/s. (i think your conversion from mbits/s to bytes/s is faulty.) also you do get 1 oustanding per read or write, not per machine. so the real limit is wire speed, but for most programs most of the time the limit for a single file transfer would be as you specify. - erik
