A command-line benchmarking tool (inspired by bench). If the program execution time is limited by disk I/O, the benchmarking results can be heavily influenced by disk caches and whether they are cold or warm.
<BR><BR>
Its features include: <BR>
<ul>
<li>Statistical analysis across multiple runs.</li>
<li>Support for arbitrary shell commands.</li>
<li>Constant feedback about the benchmark progress and current estimates.</li>
<li>Warmup runs can be executed before the actual benchmark.</li>
<li>Cache-clearing commands can be set up before each timing run.</li>
<li>Statistical outlier detection to detect interference from other programs and caching effects.</li>
<li>Export results to various formats: CSV, JSON, Markdown, AsciiDoc.</li>
<li>Parameterized benchmarks (e.g. vary the number of threads).</li>
</ul>
