Linux 下的 time 命令可以获取命令执行时间Windows 下并没有类似的命令我们可以自力更生写一个批处理命名为timebat [plain] @echo off set /a StartMS=%time:~%* + %time:~%* + %time:~%* + %time:~%* + %time:~%* + %time:~% % % % % % % set /a EndMS =%time:~%* + %time:~%* + %time:~%* + %time:~%* + %time:~%* + %time:~% set /a realtime = %EndMS%%StartMS% echo %realtime%ms 这是执行的例子测试PHP 不同版本的运行速度 [plain] F:\BAK>timebat F:\BAK\php\phpexe primesbenchmarkphp PHP version Found prime numbers ms F:\BAK>timebat F:\BAK\php\phpexe primesbenchmarkphp PHP version Found prime numbers ms F:\BAK>timebat F:\BAK\php\phpexe primesbenchmarkphp PHP version Found prime numbers ms |
