In this two part article I will explore these features and attempt to answer the performance question with the aid of a single threaded benchmark.
在这篇由两部分组成的文章里，我将逐一探究这些特性，并尝试在单一线程基准的协助下，回答关于性能的问题。
Synchronization has always been an indispensable part of multi-threaded programs while accessing a common resource, and logging is no exception.
在访问一个公共的资源时，同步始终是多线程程序不可缺少的部分，日志记录也不例外。
In part one of this article we used a single threaded benchmark to compare the performance of the synchronized StringBuffer to the unsynchronized StringBuilder.
在本文的第一部分中，我们通过一个单一线程的基准，比较了同步的StringBuffer和非同步的StringBuilder之间的性能。
The threaded part shall withstands a force equal to the actual ultimate load of the rebar.
螺纹部分应承担受力，其等于螺纹钢筋实际的终受力。
The injection machine pushed the knockout plate, and then the knockout plate drove the threaded rod, resulting in the rotation of the threaded core and the auto_demoulding of the plastic part.
模具的特点在于利用注塑机顶出动作，由推板驱动螺杆，经齿轮传动使螺纹型芯旋转，塑件自动脱出。
For the most part, these features were incompatible with multi-threaded applications and produced inefficient code.
这些功能大部分与多线程应用程序不兼容，并会使代码效率低下。
