* simplebench/bench-backup: add --drop-caches argumentVladimir Sementsov-Ogievskiy2021-05-041-1/+10
| | | | | | | Add an option to drop caches before each test run. It may probably improve reliability of results when testing in cached mode. Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>
* simplebench: bench_one(): support count=1Vladimir Sementsov-Ogievskiy2021-05-041-1/+4

* simplebench: bench_one(): add slow_limit argumentVladimir Sementsov-Ogievskiy2021-05-041-1/+13
| | | | | | | Sometimes one of cells in a testing table runs too slow. And we really don't want to wait so long. Limit number of runs in this case. Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>
* simplebench: move results_to_text() into separate fileVladimir Sementsov-Ogievskiy2020-12-181-31/+0Star
| | | | | | | | | | Let's keep view part in separate: this way it's better to improve it in the following commits.

* scripts/simplebench: use standard deviation for +- errorVladimir Sementsov-Ogievskiy2020-12-181-5/+6
