Timed Commands

 Before Windows Vista and Windows 7called timeit.exe was a great tools to use in performance testing for tools.  I've used it to measure effective transfer rates of command line tools.  In Windows 7, the powershell command measure-command works great in some cases.  I've written this script to aid this time monitoring that should work in all Windows versions.

PoweShell Example output

PS C:\> measure-command { notepad }
Days              : 0
Hours             : 0
Minutes           : 0
Seconds           : 0
Milliseconds      : 3
Ticks             : 34410
TotalDays         : 3.98263888888889E-08
TotalHours        : 9.55833333333333E-07
TotalMinutes      : 5.735E-05
TotalSeconds      : 0.003441
TotalMilliseconds : 3.441

DOS Script that will measure how long notepad.exe will run.  Replace the command to fit your needs.
