ssh -X always seems to work for me...if you only need one application

Yeah, certainly using a system that basically ships screenshots back and forth is always going to suck compared to a proper X client - server setup. I'm not really aware of compression under bog standard X connections, but ssh certainly compresses with zlib across the network to further squeeze the best out of the bandwidth. Having said that there is implictly an overhead in the ssh encryption in terms of packets, but as above, the zlib may win over all.

`ssh -X -C` will compress your session. I use it all the time and it's much faster.
