require 'benchmark' n = 1_000_000 s = " : : : " Benchmark.bm do |x| x.report("tr:") { n.times{ s.tr(":", ";") } } x.report("tr_s:") { n.times{ s.tr_s(":", ";") } } x.report("gsub:") { n.times{ s.gsub(":", ";") } } end
Right, tr beats the other methods:
user system total real
tr: 2.760000 0.120000 2.880000 ( 2.897022)
tr_s: 5.310000 0.240000 5.550000 ( 5.822026)
gsub: 8.850000 0.200000 9.050000 ( 9.311452)
