From b6970d43f97325c9acc7bd942dcd192586d8d407 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Mon, 11 Jan 2016 10:01:44 -0600 Subject: [PATCH 104/124] Increase the ext4 default commit age Both the VM and EXT4 have a "commit to disk after X seconds" time. Currently the EXT4 time is shorter than our VM time, which is a bit suboptional, it's better for performance to let the VM do the writeouts in bulk rather than something deep in the journalling layer.
