Subject: [PATCH blktests v3 09/12] common/fio: Limit number of random jobs
Date: Wed, 3 May 2023 10:02:55 +0200 [thread overview]
Message-ID: <20230503080258.14525-10-dwagner@suse.de> (raw)
In-Reply-To: <20230503080258.14525-1-dwagner@suse.de>
Limit the number of random threads to 32 for big machines. This still
gives enough randomness but limits the resource usage.
