Timethis

Timethis is a command-line tool that helps you figure out how long it takes Windows to execute a .bat or .cmd command, namely the start, end and elapsed time. It can be used to test the execution time of files, folders or programs.

The usage is TIMETHIS "command", where the command refers to the name and format of the file you want to test (or command), along with any optional arguments. The utility takes note of the start date and time (in hours, minutes and seconds), waits for the process to finish, and lists the end date and time, along with the duration (in hours, seconds and milliseconds).

Worth mentioning is that the software application doesn't simulate the actions of the processes, but actually executes them in real time. For example, if you want to find out how its takes the OS to install a specific program, it's necessary to finalize its setup to complete the time measurement.

It's part of the Windows Resource Kits, which contain advanced utilities dedicated to IT professionals for system troubleshooting, network deployment, policy-based administration, performance, server and Active Directory management, as well as clustering and load balancing, among others.
