I don't think you can with Intellij, you either have to use a profiler like Yourkit to profile the code or use some primitive benchmarks using System.currentTimeInMillis(). Alternatively you can use Apache Commons StopWatch to do some benchmarking:

我不认为您可以使用Intellij，您必须使用像Yourkit这样的分析器来分析代码或使用System.currentTimeInMillis（）使用一些原始基准。或者，您可以使用Apache Commons StopWatch进行一些基准测试：

StopWatch stopwatch = new StopWatch();
stopwatch.start();
... some code...
stopwatch.stop();
long timeTaken = stopWatch.getTime()

EDIT: There is a plugin available for Intellij that uses VisualVM to do profiling, you could install this as another alternative.

编辑：Intellij有一个插件可以使用VisualVM进行分析，你可以安装它作为另一种选择。
