如果你在多核机器上运行单线程的应用程序，就要禁用除第一个核以外所有核的优化，这样会使应用程序运行得更快。
If you run a single-threaded application on a multi-core machine you might even make your application run faster by switching off all but your first core.
在效果上，同步的误用，会把应用程序变成单线程应用程序，从而降低吞吐率。
In effect, misuse of synchronization can turn the application into a single-threaded application, thereby decreasing throughput.
如刚刚提到的，遗留应用程序的单线程特性就是遗留系统技术限制的一个例子。
The single-threaded nature of legacy application, like that just mentioned, is an example of a technical limitation of a legacy system.
