Easy way to benchmark ruby code

As I was pounding away at the language I barely understand, I started thinking... which of the two approaches is faster:

A:    Let RegEx do a case insensitive search or
B:    Downcase all of the output, and let the regex run.
`auditpol /get /subcategory:\"#{@category}\"`.match(/#{test}/i)
`auditpol /get /subcategory:\"#{@category}\"`.downcase.match(/#{test}/)

Well, apparently there is an incredibly .. retardedly easy way to satisfy that curiosity:

 The simplest way to measure your Ruby code is with Benchmark.measure
require 'benchmark'
require 'bigdecimal/math'

# calculate pi to 10k digits
puts Benchmark.measure { BigMath.PI(10_000) }

Just wow.... I don't think I ever had it that easy with measure object in powershell... to be perfectly honest, that object in powershell is borderline useless.
