Author: ivoras Date: Wed Mar 16 16:22:59 2011 New Revision: 219699 URL: http://svn.freebsd.org/changeset/base/219699 Log: The hardware has caught up; improvements are now observed even at 128, but stay conservative and bump read_max to "only" 64 (it will probably be a good idea to increase this to 128 after the next major release).
