Author: marius Date: Mon Apr 16 18:29:07 2012 New Revision: 234348 URL: http://svn.freebsd.org/changeset/base/234348 Log: Turn on PREEMPTION by default. After fixing several bugs over time, the last show-stopper keeping PREEMPTION from being usable on sparc64 should have been dealt with in r230662. At least on 2-way systems, PREEMPTION causes a little bit of a degradation in worldstone performance. However, FreeBSD seems to have started building up regressions in !PREEMPTION cases so sparc64 better should not be an oddball in this regard.
