Linux / UNIX: Speed up SSH X11 Forwarding

by

SSH X11 Forwarding can be slow, especially over long distances or low-bandwidth connections. To speed up SSH X11 Forwarding, you can make the following optimizations:

  1. Compression: Enable compression on the SSH connection by adding the -C option to the ssh command.
$ ssh -C user@host
  1. Forwarding optimization: To optimize the X11 forwarding, add the following line to the ~/.ssh/config file on your client machine:
ForwardX11 yes
ForwardX11Trusted yes
  1. Disable X11 forwarding: If you don’t need X11 forwarding, you can disable it entirely by commenting out the following line in the /etc/ssh/sshd_config file on the server:
#X11Forwarding yes
  1. Use a faster X11 implementation: If you are using X11 forwarding, consider using a faster X11 implementation such as XQuartz on MacOS or Xming on Windows.
  2. Use sshfs: Consider using sshfs to mount remote directories locally instead of X11 forwarding for a much faster experience.

These optimizations can significantly improve the speed of SSH X11 forwarding. However, the best optimization depends on your specific environment and use case, so it’s best to experiment and see what works best for you.
