Remote Firefox over SSH is pretty usable until you try a right click to make context menu show up. It takes about 5 seconds for the context menu to appear. It seems it takes many round trips.

ssh -c blowfish-cbc -C -Y host

I believe with the above command, it's more faster. I heard blowfish-cbc cipher is pretty fast while being secure. Is there anything else I should look?

But then maybe that is just placebo effect. I don't know how to time this 5 seconds event exactly.

Give FreeNX a try.

He he could just tunnel his traffic instead of pulling a remote X app over SSH. – David Rickman Sep 9 '09 at 19:29
+1 for NX. I have since dumped SSH/XDMCP for NX. – sybreon Sep 10 '09 at 0:49

Are you running Firefox on the remote end? Or are you using Firefox locally and using ssh to tunnel your HTTP traffic?

If you're actually tunneling an X11 connection over ssh, you're pretty much doing everything you can do outside of buying expensive hardware to eke out more performance. You can switch your cipher to arcfour to get a little more performance, but the security is questionable.

I'm using Firefox on the remote end. Maybe I should use NX. – RamyenHead Sep 10 '09 at 8:08
You might have to. NX is supposed to be quite good. Out of curiosity, what kind of network links are you running the forwarded session over? It really shouldn't be that terribly slow. – Josh Budde Sep 10 '09 at 14:55
