[casper] 10GbE throughput

2014-03-13 Thread Jack Hickish
Hi all, I have an application that generates 40 Gb/s of data and I'd like to output it over 4 x 10GbE links (i.e. one roach2 mezzanine card). I'm going to have to throw some data away to make room for packetising overhead, and right now I'm trying to work out how much, to see whether I should
