bm(label_width = 0, *labels) {|report| ...} in Ruby
By: Jeya in Ruby Tutorials on 2009-03-03
A simple interface to the benchmark method, bm is generates sequential reports with labels. The parameters have the same meaning as for benchmark.
require 'benchmark'
n = 50000
Benchmark.bm(7) do |x|
x.report("for:") { for i in 1..n; a = "1"; end }
x.report("times:") { n.times do ; a = "1"; end }
x.report("upto:") { 1.upto(n) do ; a = "1"; end }
end
Generates:
user system total real
for: 1.050000 0.000000 1.050000 ( 0.503462)
times: 1.533333 0.016667 1.550000 ( 0.735473)
upto: 1.500000 0.016667 1.516667 ( 0.711239)
