When I run the interface in 100 Full half or full duplex, throughput is awful, ie; 8-10k/sec on ftp's. If I run in 10 Full, same thing, but in 10 half, throughput goes up to the 700-850k/sec ranges. This is on a 'dc0' interface. It's connected to a HP pro-curve 4108 and I've checked for mismatch modes. The man pages (4) on dc reference problems on either 100 modes. I'd sure like to get better throughput out of this card. Bill Harris Director of Technology Royse City ISD (972)-635-5050
