Hi,

I’m running a Ruby script which loads about 80 ruby files through  
require. On Linux it takes no time to load and run. But on windows it  
takes ~10 seconds just to load the files.

Why is Ruby on Windows so slow to load files? Can I do anything about  
it? (other than not loading them)

Thank you,

Ittay

Are those files on a network file system? Do you have a virus scanner?
