The windows machine identifies it's SSH implementation as "SSH
implementation = http://3sp.com_Maverick_SSHD"
The AIX box is using OpenSSH 4.7

This is on a private circuit between two companies - no ISP involved.
Also no throttling on the circuit or QoS either.

Oddly enough, I have the Windows admin doing that very thing right
now. Sadly, that isn't going to correct the problem long term as the
Windows machine is running some software from a company I cannot name
(corp NDA) which handles incoming connections. The SSH implementation
is baked into their software so if I do find that it doesn't play well
with OpenSSH 4.7 Im going to require a patch from them.

All getting a bit complex for this list, and technically it's got
nothing to do with Ubuntu Linux either. Thanks for the feedback on the
speed though. Sadly, we have a difference of opinions in that one camp
says it's typical and another says it's well out of order.
