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
