**TimedExec** is a small utility for *benchmarking* command-line programs. It will *execute* the specified program with the specified command-line arguments and then *measure* the time that it takes for the program execution to complete. In order to obtain *accurate* results, all measurements are implemented via *high-resolution* performance timers. And, since program execution times unavoidably are subject to variations (due to environmental noise), each test will be repeated *multiple* times. The number of metering passes can be configured as desired. TimedExec will then compute the *mean* execution time of all passes. It will also record the *fastest* and *slowest* execution time. Furthermore, TimedExec computes the *standard error* as well as the *confidence interval* from the benchmarking results. This is the *range* which contains the program's actual (mean) execution time, *with very high probability*. Last but not least, an optional number of "warm-up" passes can be performed *prior to* the first metering pass. The warm-up passes prevent caching effects from interfering with the execution times. Note that all benchmarking results will be saved to a log file.
TimedExec uses a very simple command-line syntax. Just type "TimedExec", followed by the program that you want to benchmark, followed by the desired arguments.
In the following example we use *TimedExec* to benchmark the program **ping.exe** with the arguments **-n 12 www.google.com**. The command will be executed ten times, by default:
