Subject: Performance with unified IPv4/IPv6 tap queues
Date: Thu, 10 Oct 2024 20:11:57 -0400	[thread overview]
Message-ID: <70acdd85-5dda-4bb1-b54c-e5e7d2f4d5ff@redhat.com> (raw)

Hi all,
I added the addressing/routing workarounds suggested by Stefano, and
the performance measurements now seems to be working flawlessly,
even the one Stefano said failed in his runs.

I made 5 runs from the master branch, and 5 with my two patches applied.

You can observe the resulta at

However, there seems to be a systematic decrease in throughput.
If we take the average over the runs for IPv6 ns - > host via tap,
we get 33.56 Gb/s vs 31.84 Gb/, i.e. a 5% difference.

I don´t really know what to make of this, and would like to know if
anybody else can confirm or falsify this.
