> means you usually only see 3-5 mb/s I see over 50Mb/s (=~400Mb/s) on a gb network without any attempts at optimization, between a stupid Atom machine and a fast machine, both running Linux (which other responders claim is unoptimized). When did you last test? Also, this might be the speed of the disks at one of the ends - I've never even bothered to check, because making it faster doesn't make a difference for me.

My experience with a 20-disk RAIDZ3 machine and my desktops has always been that SSH tops out at 3-5mb/s, which was why I could never understand the prevalence of advice to "just do your disk backup over SSH". The same disks Samba between Windows and Linux achieve 70-90 mb/s, and switching to HPN-SSH (in either Cygwin or Linux) gives me the same sort of speeds with the AES cipher or none cipher. These are not slow machines - i7's and i5's. I've never been able to find a compelling explanation as to how this could be when other network protocols can manage it just fine.

  (I wanted to write 50MB =~ 400Mb earlier). Something in your setup is broken. I get 50MB/s speeds when Linux is on both ends, and even when Cygwin is on one end.
