You have the right idea, except a more precise timing is available with the microtime() function. the parameter to pass is an integer denoting the UNIX Timestamp. And the value of CLOCKS_PER_SEC in my comp is 1000000. In the above example we initialize a variable containing begin of operation milliseconds, again have PowerShell count from 1 to 10000, set another variable at the end of the cycle and finally print out difference between the start and end time giving us elapsed milliseconds.
