A little utility to make
take much less time.
Well, mostly on windows–on linux it's a speedup of only 0.41 to 0.45s, or so. 
If you've ever wondered why ruby feels slow on doze…sometimes it's just the startup time. This helps.
loading a spec file:
1.9.1 without 3.20s with 0.34s (10x improvement) 1.8.6 without 3.6s with 1.25s
rails app, running script/console “puts 333”
1.9.1 without: 20s with: 10s 1.8.6 without: 9s with: 6s
1.9.1 without: 3.75s with: 1.5s 1.8.6 without: 1.37s with: 1.25s
Note: in reality what we should do is fix core so that it doesn't have such awful I/O time in windows. There may be some gross inefficiency in there. For now, this is a work-around.
A sister project to this one, faster_gem_script, can make ruby scripts in linux run faster by 0.1s :) github.com/rdp/faster_gem_script
(in windows it's a much higher gain). Eventually they'll be combined into one “gem optimizer” gem.
