Subject: [PULL 1/9] simplebench: bench_one(): add slow_limit argument
Date: Tue, 4 May 2021 12:01:05 +0300 [thread overview]
Message-ID: <20210504090113.21311-2-vsementsov@virtuozzo.com> (raw)
In-Reply-To: <20210504090113.21311-1-vsementsov@virtuozzo.com>
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.
