Measure and Benchmark Time for Ruby Methods

Question

How can i measure the time taken by a method and the individual statements in that method in Ruby. If you see the below method i want to measure the total time taken by the meth

Answer 1

The simplest way:

require 'benchmark'

def foo
 time = Benchmark.measure {
  code to test
 }
 puts time.real #or save it to logs
end

Sample output:

2.2.3 :001 > foo
  5.230000   0.020000   5.250000 (  5.274806)

Values are: cpu time, system time, total and real elapsed time.
