Another reason is because when the JVM manages lock acquisition and release using synchronization, the JVM is able to include locking information when generating thread dumps.

另一个原因是因为，当jvm用synchronized管理锁定请求和释放时，JVM在生成线程转储时能够包括锁定信息。

This change amortizes the cost of the lock acquisition over many packets and reduces lock contention significantly, allowing us to scale memcached to 8 threads on an 8-core system.

这个更正将请求锁的开销平摊到了多个数据包，显著地减少了锁争 用，这样我们就能在8核系统上将memcached伸展至8线程。

Buffer acquisition is managed through the use of latches, known as mutex, and lock-access information.

缓冲区的获取是通过使用锁存器（latch）和锁访问信息来管理的，该锁存器称作 mutex。
