to pre compile your css and js for testing the live version locally

config/environments/production.rb - change to true

in console:

rake assets:precompile <- compiles all assets rails server -e production <- starts server in production state

to run on a different port

rails server -p 3001 <- or whatever port you want to use

browsers can help

yslow.org chrome - pagespeed extension

if you have to load multiple scripts and you're using cdn hosted scripts, using different servers can speed things up as it reduces script blocking (the browser has to wait for the server to respond before it starts it's next request).
