I've done this quite a bit and have not seen this problem
x2go client on ubuntu --(a)--- AWS EC2 Ubuntu desktop ---(b)--- AWS EC2 Windows 2003 serverl
- link (a) is 15 Mbs cable connection
- link (b) is 10Gbps ethernet
A few thoughts I'd have are:
- is only RDP affected?
- From x2go client can you log into the x2go server and do an extended PING (say 20 iterations or so) to the Windows Server to see if PING's response time is changing?
- are you sure there are no network issues on the link btwn the x2go server to the windows server? as it sounds like the VPN test went directly to the Windows server leaving out the link between the x2go server and Windows Server
- Are you able to log directly into the x2go server ...not using x2go ... and run rdesktop directly to the window server just to see if RDP is having a problem over that link?

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
