From 858e145b7814df072f75de33ddb888b042787081 Mon Sep 17 00:00:00 2001 From: Denis Nikitin Date: Mon, 16 Sep 2019 15:30:05 -0700 Subject: toolchain_utils: Reduce CPU freq in nightly tests The change should provide more stable performance results on ARM devices by reducing CPU frequency below 95% of max freq. Experiments show that second from highest frequencies on kevin64 and scarlet reduce the noice on octane, aquarium and loading.desktop by 20-50%. BUG=chromium:966514 TEST=95% freq tested on scarlet and kevin64.
