The time (microseconds) to perform the transaction for a single node were 1877 with regular locking, 1225 with an explicit write lock, and 181 using a "dirty interface".
完成一个事务的时间（以毫秒计）在单节点上是：常规锁——1877，显式写入锁——1225，而使用“脏接口”的话是181。
Given the single threaded nature of this benchmark, I was fully expecting Escape Analysis to elide the lock thus rendering StringBuffer performance equivalent to that of StringBuilder.
明确了这个基准测试的单线程化的本质后，我期待着逸出分析会消除锁，从而将StringBuffer的性能提到了与StringBuilder相同的水平。
In the case of this single threaded benchmark, it is quite safe for Hotspot to safely elide the lock.

The compiler can observe that there is a sequence of adjacent blocks that operate on the same lock, and merge them into a single block.
编译器可以观察到有一个顺序的相邻块对同一个锁进行操作，并会把它们合并到单一块内。
If after replacing these with a single table lock, the MAXLOCKS value is no longer exceeded, lock escalation stops.
如果用一个表锁替换这些行锁，将不再会超出maxlocks值，那么锁升级就会停止。
The previous example showed how to gather information about lock-timeout events for a single workload.
前一个例子演示了如何收集单个工作负载的锁超时事件信息。
Then we can replace all four calls to acquire the lock with a single one that surrounds the entire method body.
然后我们只需执行一次获取锁的操作（为整个方法），而不必像以前一样获取四次锁了。
If only a single type of lock can be associated with the given table, then it may make sense to add extra columns to the original table to control the locking.
如果只有单一类型的锁关联到给定表，那么可以添加额外的列到原始表中来控制锁定。
Having a single thread pool could cause significant lock contention.
使用单独一个线程池可能会导致严重的锁争用。
Even when run with a single thread, the collapsed version was some 30 percent faster: it is much faster to acquire a lock that you already hold than one that nobody holds.
即使只运行一个线程，崩溃版的速度也要快约30%：获取您已占用的锁比获取无人占用的锁要快得多。
Training to improve finger strength, getting better at lock-offs, and even back-stepping (the single most useful technique in all of climbing!
增强指力，更有力的锁住支点，甚至是转身（唯一一个最有用的攀爬技巧！）
This means that multiple threads can access different portions of the Map simultaneously, without contending for the single collection-wide lock.
这意味着多个线程可以同时地访问一个Map的不同部分，而不必争用单个的集合范围的锁。
Pthread_mutex_lock accepts a single pointer to a mutex to lock.
pthread _ mutex_lock接受一个指向互斥对象的指针作为参数以将其锁定。
If you have a single threaded program, you don't need a lock.
如果你有一个单线程程序，您不需要锁。
This situation is equivalent to having acquired the lock: when there is only a single thread, all object accesses are safe.
这种情况等同于已经获取了锁：只有一个线程的时候，所有的对象访问都是安全的。
It is the lightest as execution time, often a lock or unlock becomes just a single inlined assembler instruction.
就运行时间而言是最轻便的，大多数情况下只需要单条内联汇编指令就可以上锁或解锁。
I have students do an electronic code lock, single chip, it should be useful.
我同学做的电子密码锁，单片机的，应该有用。
Accordance with the traditional film printers weakness in locking of laser intensity, a new automatic lock technology based on single chip microcomputer was presented in this paper.
针对激光照排机光强锁定中存在的问题，提出了基于单片微型计算机系统的自动锁定技术。
