Subject: [dpdk-users] Proper configuration of pktgen
Date: Wed, 14 Apr 2021 15:32:32 +0200	[thread overview]
Message-ID: <99159c11-ed64-9e98-5c3a-a0ee3dc200b5@filipjaniszewski.com> (raw)

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
