Short-lived benchmarks (benchmarks that complete in a very short period
of measured time) are often more affected by jitter and warm-up effects
than longer running benchmarks. Since QBENCHMARK stores the median
result of all accepted benchmark runs, a larger number of aggregation
runs is preferable for short-lived tests, but not necessarily for longer
running ones. The minimumtotal option, specified in units of the
selected measurement, will make the benchmark repeat a benchmark until
the total measured cost exceeds the specified threshold. The displayed
median result will then tend to be more accurate. This is especially
useful for data-driven benchmarks in case the data tags scale the
benchmarked operation from little to large cost.
