是否有内置的方法可以测量Windows命令行上命令的执行时间?

Is there a built-in way to measure execution time of a command on the Windows command line?

推荐答案

如果使用的是Windows 2003(请注意，不支持Windows Server 2008和更高版本)，则可以使用Windows Server 2003资源工具包，其中包含timeit.exe.显示详细的执行状态.这是一个示例，对命令"timeit-?"进行计时:

If you are using Windows 2003 (note that windows server 2008 and later are not supported) you can use The Windows Server 2003 Resource Kit, which contains timeit.exe that displays detailed execution stats. Here is an example, timing the command "timeit -?":

C:\>timeit timeit -?
Invalid switch -?
Usage: TIMEIT [-f filename] [-a] [-c] [-i] [-d] [-s] [-t] [-k keyname | -r keyname] [-m mask] [commandline...]
where:        -f specifies the name of the database file where TIMEIT
                 keeps a history of previous timings.  Default is .\timeit.dat
              -k specifies the keyname to use for this timing run
              -r specifies the keyname to remove from the database.  If
                 keyname is followed by a comma and a number then it will
                 remove the slowest (positive number) or fastest (negative)
                 times for that keyname.
              -a specifies that timeit should display average of all timings
                 for the specified key.
              -i specifies to ignore non-zero return codes from program
              -d specifies to show detail for average
              -s specifies to suppress system wide counters
              -t specifies to tabular output
              -c specifies to force a resort of the data base
              -m specifies the processor affinity mask

Version Number:   Windows NT 5.2 (Build 3790)
Exit Time:        7:38 am, Wednesday, April 15 2009
Elapsed Time:     0:00:00.000
Process Time:     0:00:00.015
System Calls:     731

您可以在Windows 2003 Resource Kit中获得TimeIt.它不能从Microsoft下载中心直接下载，但是仍然可以从

You can get TimeIt in the Windows 2003 Resource Kit. It's not available for direct download from the Microsoft Download Center, but one can still get it from the arhive.org - Windows Server 2003 Resource Kit Tools.
