Hi, I'm trying to generate 56G worth of data with pktgen (on a 56G link with two mellanox endpoints), using this simple configuration:
. pktgen -l 5-19 -- -P -m "[6:10-19].0" . On a Linux machine that is doing nothing but running pktgen, with such a command I'm able to send around 50G of data, or 77Mpps, adding one more cores (9-19) Improves the performance of around 1G, up to 78Mpps, adding even more cores does not help at all. Am I hitting some hardware limits here or there's some more advanced configuration I should use to run pktgen? Any suggestion would be appreciated. Thanks -- BR, Filip +48 666 369 823
