From 99777f60342ce1371e3960661035ca7cd89f96f5 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Mon, 27 Jan 2014 14:39:48 +0000 Subject: local.conf.sample: Add automatic defaults for BB_NUMBER_THREADS and PARALLEL_MAKE Its rather sad that people don't appear to read local.conf and then complain about slow builds when they're just using a single thread. Most systems have more than one core now so we might as well use a more automatic default for these values. This may lead to better experiences for new users.
