What does "non-native" mean in this context? It certainly is native x86 code
running on an x86 machine.

It's not Exceed, FWIW; it's Cygwin XFree86: http://cygwin.com/xfree/

I'm using xterm to launch emacs, but I'm confused by your question because I
can't see how it's relevant. The slowdowns only occur when emacs isn't
running in a terminal window.

Okay. I'm not sure what it means to "switch the SSH client". I have two ways
of starting ssh:

1. From within a dos box running cygwin. It doesn't know about my DISPLAY
and thus I don't bother with -X

2. From within an xterm window I launch on my local machine from within TWM
under cygwin/XFree86

Outside means I pick the "Cygwin Bash Shell" from my start menu and get a
"dos box" running bash, with no X server running. When I launch emacs it's
running in a character-based mode.

If you have slowdowns with plink, why do you think I'll see an improvement
by switching to its terminal window?

Uhhhm. Coming up with the correct DISPLAY variable setting for the remote
machine is difficult, isn't it?
Well, OK, I tried it. And it made... no perceivable difference :(

Do you know where I can find a Cygwin version of this tool (or the
equivalent)?
