Startable

public class DisruptorFactory
extends Object
implements Startable

SLEEPING is a better option when you have a large number of event processors and you need throughput when you don't mind a 1ms latency hit in the worse case. BLOCKING has the lowest throughput of all the strategies but it does not have the 1ms latency spikes of SLEEPING. It uses no CPU when idle but it does not scale up so well with increasing numbers of event processors because of the contention on the lock. YIELDING and BUSY_SPIN have the best performance for both throughput and latency but eat up a CPU. YIELDING is more friendly in allowing other threads to run when cores are limited. It would be nice if Java had access to the x86 PAUSE instruction to save power and further reduce latency that gets lost due to the wrong choices the CPU can make with speculative execution of busy spin loops. In all cases where you have sufficient cores then all the wait strategies will beat pretty much any other alternative such as queues.
