如何编写简单的批处理文件来衡量基于控制台的应用程序的性能？控制台应用程序接受两个命令行参数.
我想得到：
StartTime = System Dos time myconsoleapp arg1,arg2 StopTime = System Dos Time timeDelta = stoptime - starttime
纯批量解决方案可能是.

set "startTime=%time%"
for /L %%n in (1,1,1000) do <nul set /p "="
set "stopTime=%time%"
call :timeDiff diff startTime stopTime
echo %diff% milli seconds
goto :eof
:timeDiff
setlocal
call :timeToMS time1 "%~2"
call :timeToMS time2 "%~3"
set /a diff=time2-time1
(
ENDLOCAL
set "%~1=%diff%"
goto :eof
)
:timeToMS
::### WARNING,enclose the time in " ",because it can contain comma seperators
SETLOCAL EnableDelayedExpansion
FOR /F "tokens=1,2,3,4 delims=:,.^ " %%a IN ("!%~2!") DO (
set /a "ms=(((30%%a%%100)*60+7%%b)*60+3%%c-42300)*1000+(1%%d0 %% 1000)"
)
(
ENDLOCAL
set %~1=%ms%
goto :eof
)
