You can use "measure" command to check performance in IRB like below: irb(main):001:0> 3 => 3 irb(main):002:0> measure TIME is added. => nil irb(main):003:0> 3 processing time: 0.000058s => 3 irb(main):004:0> measure :off => nil irb(main):005:0> 3 => 3 You can set "measure :on" by "IRB.conf[:MEASURE] = true" in .irbrc, and, also, set custom performance check method: IRB.conf[:MEASURE_PROC][:CUSTOM] = proc { |context, code, line_no, &block| time = Time.now result = block.() now = Time.now puts 'custom processing time: %fs' % (Time.now - time) if IRB.conf[:MEASURE] result } https://github.com/ruby/irb/commit/3899eaf2e2
