[PATCH v2 7/8] simplebench/bench-backup: add --count and --no-initial-run |
Date: |
Thu, 4 Mar 2021 13:17:37 +0300 |
Add arguments to set number of test runs per table cell and to disable
initial run that is not counted in results.
It's convenient to set --count 1 --no-initial-run to fast run test
onece, and to set --count to some large enough number for good
precision of the results.
