Hi Brian,

Thanks a lot for your tips to improve the performance. So now, I am going to try:

1) If download link is good then I will try "LAN" settings
2) When it is in wireless network , I will try "WAN" settings. 

Yesterday, I tried different settings using LAN, WAN, ADSL with simulated latency but I was not able to identify the difference between different settings. I might need to run some youtube video to see the difference. 

Thanks again for your help.

I should have added a little more info related to this.

I use Amazon's EC2 cloud quite a bit with x2go.

My AWS EC2 server runs ubuntu 13.10 x64 and I have the x2goserver installed on it with the xubuntu-desktop (re xfce desktop).

However, on that server I think installing xubuntu-desktop must have auto-magically installed "libjpeg-turbo-progs" because I did not have to install it manually.

My home PC has an 18Mbps downlink from the internet and a 3 Mbps uplink (I use ATT uVerse).

Now regards the X2GO client CONNECTION SETTINGS.

Setting the Client to WAN
  • logging into the AWS x2goserver's XFCE and then running firefox I goto youtube and play a music video.
  • video is a bit choppy (I know that's subjective <g>).

Setting the Client to LAN (no compression)
  • logging into the AWS x2goserver's XFCE and then running firefox I goto youtube and play a music video.
  • video is almost perfect - re less choppiness than with Client set to WAN.
So at least in my experience whether you set the Client to WAN or LAN "may" depend on your downlink speed from the remote x2goserver.
If you have a fast enough WAN connection at your client you may find doing no compression at all (re LAN) provides a better experience.

Lastly, don't forget to consider what your "local" lan consists of.    If your Client PC is on a Wireless network and sharing that Wireless network with
multiple other Wireless network users you may find that your wireless network is having a bigger impact on QoS of the video in the remote desktop
than the remote server, local PC or the WAN.

Mike, Shah et al

I've used libturbo-jpeg for a couple years with x2go after I first learned about it.

You might check your Distro...  but at least for Ubuntu I believe libturbo-jpeg is the default installed by Ubuntu now.

     NOTE:   in the following - I did have to install "libjpeg-turbo-progs" separately

On my Ubuntu 13.10 x64 system if I run Synaptic and search for "libturbo" I find:
Independent JPEG Group's JPEG runtime library (dependency package)
 
libjpeg8 dependency package, depending on libjpeg-turbo8.
You might do the same on your Distro to find out what libjpeg is being used today.
