Hi all,
I want to discuss the subject.
Story goes like this: About 6 months, while planning upgrade (Ununtu 11.04->11.10) I've noticed severe degradation in speed of NX sessions. At the time I've decided to wait until LTS release, while being sure issue is related to GUI changes in Ubuntu. Recently I've reviewed the situation with 12.04 and found that problem is still there and related to NX and not to GUI changes in Ubuntu. My guess is that surrounding changes in distribution cause NX agent to misbehave.
Overall user experience became unusable even on LAN and localhost connections.
Now to the details:
- Screen redraw operations lags heavily even on local links. Instant (sub 0.5sec) on U10.04, up to 5 seconds on U12.04.
- Constant screen redraws consume much more traffic. Sub 100kbps on U10.04. 10mbps+ on U12.04 (Creating session with WAN quality settings and reconnecting with LAN, lowers bandwidth to sub 1mbps but picture quality suffers)
- NX4 on U12.04 is faster 3x (in average) than 3.5 on U10.04.
- NX3.5 on U12.04 is slower 3x then NX3.5 on U10.04 (some tests are x1000 slower!)
- Hybrid NX3.5<->NX4 is slow with NX3.5 as server and fast with NX4 as server.
Some details:
- I've evaluated both 32 and 64 bit platforms.
- I've compared fresh Ubuntu 10.04 and 12.04.
- Both Nomachine NX binaries and X2GO binaries (ppa:x2go/ppa) were tested.
- For reference I've performed NX4 and hybrid NX3.5<->NX4 testing.
- Tested several usecases:
- Desktop with manual operation of terminal, webbrowser and random GUI application.
- Rootless UnixBench in graphics mode. (Note in 64bit test caches NX agent!)
- Desktop UnixBench in graphics mode. (Note in 64bit test caches NX agent!)
- Rootless Xterm with scrolling text (ls -R /)
Please provide your feedbacks.
Did you make sure you have the same connection settings (Network, Image compression, etc)
Cheers Morty

Yes, I've used same hardware with identical connection settings. Also I've validated connection settings reported by NX during session setup. NX3.5 behaves bad no matter which network media used, I've tested with: 1000Gbit Lan, 100Mbit Lan, 50Kbit WAN, 100Kbit WLAN and localhost (127.0.0.1). To exclude specific hardware problems, several key tests were performed on several different machines.

Unity does not work using x2go, try installing gnome 2.3 or xfce and launching the session.
When i tried x2go and nx with unity it was really laggy because of the open gl display.

Hi all,
same here. I have a Ubuntu 9.04 with x2go based on NX3.4 and now a Ubuntu 11.10 with x2go based on NX3.5.
I open a terminal (gnome-terminal) an do a cat /var/log/sysolg.
The old server (NX3.4) uses 30kb traffic for 2 seconds to cat the logfile. The new server (NX3.5) uses 750kb traffic for 34 seconds to cat the logfile.
