At a later point in time, the reader thread invokes the read operation on the channel (this is also a synchronized method, so the reader thread must acquire the monitor lock before proceeding).
稍后，阅读器线程调用通道上的read操作(这也是一个同步的方法，所以阅读器线程在继续处理之前必须得到监视器锁)。
In each case, I ran a simple program that measured the run time of a loop calling a method 10,000,000 times, calling both a synchronized and an unsynchronized version, and compared the results.
在每一个实例下，我运行一个简单的程序，测定循环调用一个方法10,000,000次所需的运行时间，我调用了同步和非同步两个版本，并比较了结果。
Thus, you cannot use the form GET method if you want your content to be synchronized properly.
因此，如果想要内容被适当地同步，那么便无法使用表单GET方法。
A synchronized call to an empty method may be 20 times slower than an unsynchronized call to an empty method, but how often do we call empty methods?
对一个空方法的同步调用可能要比对一个空方法的非同步调用慢20倍，但我们多长时间才调用一次空方法呢？
Creating the synchronized block yielded 16 lines of bytecode, whereas synchronizing the method returned just 5.
创建同步代码块产生了16行的字节码，而创建同步方法仅产生了5行。

一个“同步”异步方法的开销是多少？
If one thread invokes this method frequently, other threads that also need frequent synchronized access to the same object will often be blocked.
如果一个线程频繁调用这个方法，其他的线程也需要频繁的同步访问同一个对象，这就会造成阻塞。
However, because the method is synchronized, you pay the cost of synchronization for every invocation of the method, even though it is only required on the first invocation.
尽管如此，由于该方法是synchronized的，需要为该方法的每一次调用付出同步的代价，即使只有第一次调用需要同步。
Even if there are other statements between the synchronized blocks or method calls, the compiler can still perform lock coarsening.
即使在synchronized块或方法调用之间有其他语句，编译器仍然能够执行锁粗化。
