X11 slow performance speeds over WAN

[jdebusk]

Hi all,

I currently ssh into my CentOS 7 at home via PuTTY and everything works perfectly, until I attempt to open any windows such as a browser. (I have google-chrome, konqueror, and firefox, all of which are really slow.)


I have 22mb/s down / 4 mb/s up internet connection. It's rock solid. When I use something like TeamViewer, there isn't any performance issues. However, when I type "/usr/bin/(insert google-chrome, firefox, or konqueror)" it works....but extremely slow. I don't even attempt to actually launch the desktop "startkde&" as it would take FOREVER.

I am using compression for the data. Also, I am using arcfour256 cipher. Also, it says something about a deprecated signal when I launch the browser from CLI. Let me know what other information you may need.

I've noticed that X apps run very slowly when I try to pipe them back over SSH. I have had much better results using X2Go, which I installed from the EPEL repository. X2Go does a lot of protocol compression on X, as did NX from which it apparently evolved. I have a network connection similar to yours (cable asymmetrical broadband, 25 Gbps down, 5 up) and regularly use it from work, and from home to get to systems at work. By default it is tunneled through an SSH connection, if security is a concern.

Just my $.02!
