Nobody is really doing this, or they aren't talking about it.
Sometimes the crash fixes and other work completely consumes us.  Add
in travel to conferences and real life, and it's no surprise stuff
like this slips through the cracks.

We absolutely depend upon people like you to report when there are
anomalies like this.  It's the only thing that scales.

FWIW I have a t1000 Niagara box and an Ultra45 going through a netgear
gigabit switch.  I'm getting 85MB/sec in one direction and 10MB/sec in
the other (using bw_tcp from lmbench3).  Both are using identical
broadcom tigon3 gigabit chips and identical current kernels so that is
a truly strange result.

I'll investigate, it may be the same thing you're seeing.
