H A D | dmu_zfetch.c | diff 193878 Tue Jun 09 23:26:59 MDT 2009 kmacy As far as I can tell systems that have less than 4GB are more often hurt by prefetched than helped. On i386 systems and systems with less than 4GB, prefetch is now disabled by default. I've added a prefetch enable tunable, to enable prefetching for those systems. The prefetch disable tunable will continue to unconditionally disable prefetching. |
