Author: cperciva Date: Sat Jul 16 08:17:14 2016 New Revision: 302931 URL: https://svnweb.freebsd.org/changeset/base/302931 Log: MFH r301732, r302288 Updates to EC2 loader.conf: * Use console=comconsole (r301732) since EC2 now has a "VGA" console; * Enable blkif indirect segment I/O (r302288) since EC2 now consistently gets better disk performance with this option enabled.
