Subject: Performance drop on SFC interface (around 30%)
Date: Thu, 16 Jun 2016 15:23:29 +0200	[thread overview]
Message-ID: <20160616132329.GA27108@redhat.com> (raw)


Hello netdev,
we see a performance drop (about ~30%) on sfc driver (SFC9020) when
performing netperf TCP maerts test. It seems it started from 4.7-rc0.

Which commit/change could cause this regression? Any hints?

I opened a bugzilla [0] where you can find images with results.
