I can FTP data from Box A or B to box C at 10MB/sec, still not the gigabit speeds i should be seeing but not the 200KB/sec i am getting with freebsd. >> >> I logged into my switch and it reports that the ports are 1000tx full duplex, the same as what freebsd is reporting.

I've tried drivers 1.9.5, 1.8.4, and 1.7.3. If i use 1.8.4 or 1.7.3 i get 50KB/sec transferring data from box B whereas if i use 1.9.5 i get 200-300KB sec. I should be getting like 50MB/sec ;( >> >> Any help would be grateful.
