Mac 上最好的免费 Java 分析器
我之前使用过 YourKit,它工作得很好,但对我来说太贵了。是否有一些适用于 Mac 且与 YourKit 一样工作的免费或开源 Java 分析器?
I was using YourKit before and it was working perfectly, but it's too expensive for my taste. Is there some free or open-source Java profiler for Mac that's working as well as YourKit?

YourKit 提供无需购买的抢先体验 (EA) 版本。它最擅长的就是在结果中汇总运行时间。如果方法 a() 只是调用其他方法,但实际花费的时间很少,那么即使方法 a() 调用花费了大量时间,它在 VisualVM 中也不会显示太多。
YourKit offers Early Access (EA) builds which do not require a purchase. The main thing it does well is aggregating run times in your results. If method a() just calls other methods but very little time is actually spent in it, it doesn't show up much in VisualVM, even if the methods a() calls spend lots of time.
