I develop software on a Macbook Air 1.6 Ghz but find running Rails test suites and generators on this computer very slow. I'm thinking about buying a Linux tower to put on my local wireless network to do my Rails development on. I would want to use my Macbook Air and ssh into the Linux box and do my development with Gnu Screen, vim, etc.
Can I expect the keystroke and echo latency for a ssh session between two machines on a local wireless network to be negligible?
Does anyone develop using this kind of local setup? What CPU speed is your Linux box?
