I have a project where I would like to use the AMC405EX under Linux for
high speed data acquisition. I have the Kilauea board in the lab but
measured only 150Mbit/s TCP throughput (outbound) with iperf. I need
twice of that and actually expecting 3x higher bandwidth from that
architecture.
what is it that I'm missing?
can anybody confirm my results or tell me what am I doing wrong?
any help is appreciated
sincerely
