Subject: [PATCH v2] multipathd: Set CPUWeight to 1000 and LimitRTPRIO to 10
Date: Mon, 15 Apr 2024 19:43:06 -0400 [thread overview]
Message-ID: <20240415234306.1984762-1-bmarzins@redhat.com> (raw)
If multipathd doesn't become a real time process, it was scheduled as a
normal process, without any priority increase. Bump up the CPUWeight so
that even as a normal process, it will still run with increased
priority.
If multipathd did become a real time process, it set itself to the
highest priority, which is excessive. A priority of 10 is plenty.

Notes:
v2: Lowered LimitRTPRIO as suggested by Martin Wilck.
