Thanks, I tried a very basic example and was trying to monitor data rate using nethogs with a different sample rate.
At a signal sample rate of 9.6MSPS, nethogs sees about 59MB/s of data. I wonder if that could be improved in anyway, or whether the sample rate of an actual wired lan connection might be better? I vaguely remember that the USB data transfer rate at 6.4MSPS was about 15MB/s.
