Introduction
============
**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 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 certain variations (e.g. due to environmental noise), each test will be repeated *multiple* times. The number of metering passes can be configured as desired. Optionally, a 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.
TimedExec will then compute the ***mean*** execution time as well as the ***median*** execution time of all metering passes. It will also record the *fastest* and *slowest* execution time that has been measured. Furthermore, TimedExec computes the *standard error* in order to determine ***confidence intervals*** from the benchmarking results^[[Konfidenzintervalle so einfach wie möglich erklärt](http://www.uni-siegen.de/phil/sozialwissenschaften/soziologie/mitarbeiter/ludwig-mayerhofer/statistik/statistik_downloads/konfidenzintervalle.pdf)]. These are the *ranges* which contain the program's “real” average execution time (expected value), *with very high probability*. All results will be saved to a log file.

Clock Types
-----------
*TimedExec* supports the following clock types:
- `WALLCLOCK` &ndash; the wall-clock time, also known as *elapsed real time* (default)
- `CPU_TOTAL` &ndash; total CPU time, i.e. sum of CPU time spent in "user" *and* "kernel" modes
- `CPU_USER` &ndash; CPU time spent in "user" mode only
- `CPU_KERNEL` &ndash; CPU time spent in "kernel" mode only
Usage Example
-------------

Standard Deviation : 7.697 seconds
Standard Error : 3.848 seconds

```
Interpretation
--------------
When comparing measurement results, the ***mean*** (average) execution time may seem like the most obvious choice. However, it has to be noted that the *mean* of a data sample is highly sensitive to “outliers” and therefore can be misleading! This is especially true, when there exists a lot of variation in the data sample. Consequently, comparing the ***median*** execution times usually is the preferable choice. That is because the *median* of a data sample is much more robust against outliers.
When comparing measurement results, the ***mean*** (average) execution time may seem like the most obvious choice.

This is especially true, when there exists a lot of variation in the data sample. Consequently, comparing the ***median*** execution times often is the better choice. That is because the *median* of a data sample is much more robust against outliers.
Furthermore, it is important to keep in mind that the *mean* (or *median*) execution time computed from a limited number of metering passes only yields an ***estimate*** of the program's “real” average execution time (expected value). The “real” value can only be determined accurately from an *infitinte* number of metering passes &ndash; which is **not** possible in practice. In this situation, we can have a look at the ***confidence intervals***. These intervals contain the “real” value, *with very high probability*. The most commonly used *confidence interval* is the “95%” one (higher confidence means broader interval, and vice versa).
