Xming display is very slow when using SSH

Question

I use SSH and Xming to run the Simics simulator and connect to some Linux guest machine. I am using x11 tunneling. The x server seems very slow, and I need to spend a lot of time to run one command on a Linux guest machine. Do you have any ideas what might cause the problem? Is this a ssh or xming protected shell problem?

Thanks.

Answer 1

Traffic compression can solve your problem. Use ssh -C

Answer 2

I am using Putty.

Including Blowfish compression at the top of the list in the Connection/SSH/Cipher node also helped a little.

Compression is included in the SSH node.
