> ### New Multiprocessor-safe Work
* Introduced a new cpu topology aware scheduler, usched_dfly, and made it the default. This scheduler implements several weighted algorithms and will first try to schedule threads to different sockets (to make best use of on-chip caches). As the load increases threads are then scheduled to real cores, and finally will be scheduled to hyper-threads. Threads with similar load characteristics tend to get spread out more. The scheduler also implements wait/wakeup pairing detection and tries to move related threads closer together to reduce inter-socket cache coherency bandwidth and share L3 caches.
* dragonfly.pool.ntp.org now exists and is used by default for network time
* LVM stripe support in rconfig
