Simple benchmark tool.

Usage:

require File.dirname(FILE) + '/benchmark'

class A def sum(n) sum = 0 1.upto(n) do |i| sum += sql(n) sleep(0.005) sum += sql(n-i) end end def sql(n) sleep(0.02) Kernel.rand(n) end end

b = Benchmark.instance(:general) b.for(A) b.for(Integer, :upto)

a = A.new a.sum(5) a.sum(3)

puts b.to_s

See example.rb for example output.
