Ssh X11 forwarding very slow using Xshell

Ssh X11 forwarding very slow using Xshell

My server is Ubuntu 12.10
And my client is Windows 7 64bit
Now I am using Xshell to connect my server via ssh
But after I forwarding X11, it's take a long time!!
after I enter
$matlab -nodesktop
it's almost take 5~10 mins to ready for use
I have found some speed up issue on the web but it's work on MAC not on
windows(Xshell)!
following is solution for mac and it's worked perfect!
ssh -c arcfour,blowfish-cbc -XC username@host
But when I use Xshell it's always think -c arcfour,blowfish-cbc -XC
usernameis my username!
Is there any other way to make it faster?
