From: Jonathan Rajotte Date: Mon, 29 Jul 2019 19:55:39 +0000 (-0400) Subject: Tune kernel parameter for babeltrace benchmarking X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=ba4e084cc3c4411b8acede7c837743c73d942f32;p=lttng-ci.git Tune kernel parameter for babeltrace benchmarking idle=poll prevent the kick in of sleep state. This is not that important for babeltrace since it is mostly userpsace, single threaded and cpu bound. cpufreq.off=1 ensures that we do not play with the frequency of the cpu. numa_balancing=disable makes sure weird numa interaction happens.
