I’ve found myself on a benchmarking kick these last couple of weeks. Sometime last week, I dug up the better-benchmark library written by Pistos. Pistos’ library is basically just a wrapper for the rsruby gem, which is more or less an interface to R (similar to what rmagick is to ImageMagick).

Combining these tools together, we can do some pretty nifty code performance analysis in very few lines of code, e.g.

require 'rubygems'
require 'better-benchmark'
 
result = Benchmark.compare_realtime(:iterations => 10) { |iteration|
  save_the_world()
}.with { |iteration|
  save_the_world_and_save_the_girl()
}
Benchmark.report_on result

I have forked better-benchmark and wrapped the library up into a RubyGem.
