Java性能计时库 [英] Java performance timing library

问题描述

我频繁地将代码包装在 System.nanoTime（）对以对其进行计时。类似于：

I frequent wrap code in a System.nanoTime() pair in order to timing it. Something like:

long start = System.nanoTime();    
methodToBeTimed();
long elapsedTime = System.nanoTime() - start;

有什么好的计时库可以解决这个问题吗？也会接受自己开发的代码。

There is any good timing library that helps with this problem? Also homegrown code will be accepted.

NB

分析器不是解决方案，因为我想要在我的单元测试中强制执行一些时间限制，所以我想计划方法以编程方式。

A profiler is not a solution here, since I want to enforce some time constraints in my unit tests, so I want to timing methods programmatically.

推荐答案

我我没有使用它，但我最近遇到了 perf4j 。

I haven't used it but I came across perf4j recently.
