Subject Re: Commit log and data separation on SSD
Date Sun, 22 Sep 2013 23:23:45 GMT
Having commit log and data directory under one SSD works well. Though it
depends a lot on the use case. I would measure the Disk utilization and see
whether it can be on one. For most of the cases, it will work fine on one
