Subject: [X2go-user] Performance issues using RDP
Hello, all.  We were very eager to experiment with TSPlus
(http://www.tsplus.net) as an alternative to Microsoft RDS.  We have
been assuming all along that performance of any RDP solution is better
in a low bandwidth WAN environment if we put X2Go in the middle of it
and run rdesktop from the X2Go Server to a local Windows server.  Our
results were very disappointing with both TSPlus and RDS and with both
rdesktop and xfreerdp.

Has anyone else experienced the same poor performance or, more
importantly, has anyone worked around it?

We noticed that screens seemed to be painting line by line - not sure if
if it is the entire screen or just the active window.  It also made
mouse movements very erratic in TSPlus + rdesktop.  TSPlus + xfreerdp
seems better.

To demonstrate this, I opened notepad in a large window in a full screen
session, typed an entire line, copied it to the clipboard and then held
down <CTL>V to paste it.  The first few lines flew but then it became
very slow and we could see the flicker of each line painting.

I also opened Internet Explorer and went to www.spiritualoutreach.org -
a very poorly designed site I put up years ago with long pages and far
too large graphics.  I sat and watched the screen paint a band at a
time.  I opened one of the large template documents and vertical
scrolling was nearly impossible.

I'll paste in some of our internal notes below.  Thanks - John
