Subject: [PATCH] arm64: defconfig: enable CONFIG_SCHED_CLUSTER
Date: Fri, 8 Aug 2025 10:55:33 +0800 [thread overview]
Message-ID: <20250808025533.6422-1-shijie@os.amperecomputing.com> (raw)
In the server, if some workload which will create lot of
tasks, and will have many task migrations, we can get better
performance when we enable the CONFIG_SCHED_CLUSTER.
For example, the Specjbb may have better performance:
Critical-jops : 26%
Max-jops : 7%
So enable it by default.
