Benchmarking Various Require Methods

Setup

To use this collection of scripts, first run setup.rb. WARNING: This will create a folder named 'require-data' and populate it with 10,000 empty Ruby scripts.

Execution

The run.sh shell script outputs the current Ruby version, then executes the three bench_*.rb scripts contained herein.

Sample Results

Here are the results running on my 2009 MacBook Pro with an SSD.
