推荐答案

如果您使用的是 Windows 2003(请注意不支持 Windows Server 2008 及更高版本)，您可以使用包含 timeit.exe 的 Windows Server 2003 Resource Kit显示详细的执行统计信息.这是一个示例，对命令timeit -?"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 .	imeit.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
Context Switches: 299
Page Faults:      515
Bytes Read:       0
Bytes Written:    0
Bytes Other:      298

您可以在 Windows 2003 Resource Kit 中获取 TimeIt.它不能从 Microsoft 下载中心直接下载，但仍然可以从 archive.org - Windows Server 2003 Resource Kit 工具.

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 archive.org - Windows Server 2003 Resource Kit Tools.
