while (server == null && count++ < 10) { // 省略。。 if (server == null) { /* Transient. */ Thread.yield(); continue; } // 省略。。 }
看代码应该是 9 年期，难道只是出让一次机会给别的线程执行？

让出线程拿到的时间片，让其他线程去竞争，Thread.sleep()会让线程阻塞在哪里，浪费 cpu 资源

看注释：A hint to the scheduler that the current thread is willing to yield its current use of a processor. The scheduler is free to ignore this hint.
实际上这个可以极大增加 CPU 利用率，Disruptor 高性能就是靠 CAS + yield |
