但反过来也正确：明智地选择垃圾收集参数实际上会使应用程序运行速度更快。
However, the opposite is also true: a wise choice of garbage collection parameters can actually make an application run more quickly.
例如，如果具有4个可运行的任务，那么fair_clock将按照实际时间速度的四分之一增加。
For example, if you have four runnable tasks, then fair_clock will increase at one quarter of the speed of wall time.
由于我对运行速度的快慢并没有什么概念，在获得实际数据之前我所进行的优化根本就是浪费时间。
Because I had no idea what was fast and what was slow, all optimization time I had spent before getting actual data was wasted.
