Comment 3 for bug 162253

Package: openssh-server
Version: 1:4.1p1-6
Followup-For: Bug #292932

 In an attempt to provide something useful to this request
(rather than my me too post a moment ago), I just ran across this:
---
http://groups.google.com/group/mailing.unix.openssh-dev/browse_thread/thread/d6f419da2faae3ad/508e0f2fb1208e7d?lnk=st&q=%22darren+tucker%22+hpn-ssh&rnum=1#508e0f2fb1208e7d

Hopefully that comes through properly. Anyway, it's a discussion
between Darren Tucker (one of the OpenSSH contributors) and Chris Rapier
(one of the HPN-SSH contributors) about the performance patch with some
suggested changes by Darren. Assuming this all goes well ultimately,
upstream might very well be including these changes.

 But for the time being, it might be nice to grab the original
HPN-SSH patch and make Darren's recommended changes and include it in
the Debian package. In another post I saw by Darren at:

http://groups.google.com/group/comp.security.ssh/browse_thread/thread/91064fcec483b534/7d2ecfbc5bd0369b?lnk=st&q=%22darren+tucker%22+hpn-ssh&rnum=2#7d2ecfbc5bd0369b

he mentions that using the none cipher probably won't increase
throughput too much as the MAC (Message Authentication Code) is usually
the bottleneck. Although, this would change probably if the previous
performance patch were also included, assuming that Darren was referring
to the MAC being the bottleneck with the currently implemented OpenSSH
buffering scheme.

 So anyway, that's all I know at this point. Something to at
least keep an eye on as more of us are working on fast network segments
and even people on high latency and possibly even slow networks look to
benefit from this.
