Dear All,
I am a researcher and I would like to benchmark the stateful NAT64
performance of OpenBSD PF.
I use a 32-core server as DUT (Device Under Test). When I use Linux for
benchmarking other stateful NAT64 implementations, I use the "ethtool -N
enp5s0f1 rx-flow-hash udp4 sdfn" command to include also the source and
destination port numbers (not only the source and destination IP
addresses) into the hash function to distribute the interrupts caused by
packet arrivals evenly among all the CPU cores.
I tried to find a similar solution under OpenBSD, but I could not. (I
used search expressions like: OpenBSD RSS receive side scaling multi
queue receiving) Perhaps it is called differently under OpenBSD, or
maybe there is no such solution at all?
Could you advise me please?
Thank you very much for your help in advance!
Best regards,
Gabor Lencse
