Max PPS out of 10G NIC?

[Andrius Lisikas]

I'm trying to get maximum PPS generated on 10G NIC using t-rex. I am trying to use one of the sample test "imix_64_fast.yaml", but I am not able to get past 14.92Mpps no matter how many cores or multipliers I specify. Is that the maximum I can get from 10G?

Hoi,

Yes, 14.88Mpps is the most you'll get based on 64b ethernet packets (with 8 bytes preamble and 12 bytes inter frame gap). 10^10 / (84*8) is 14'880'952 packets/sec for TenGigEthernet.

groet,

Pim
