[X2Go-User] Latency Issues

[bmullan]

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.
