I've been using yourkit, it's a great tool. 我一直在使用yourkit，这是一个很棒的工具。 I normally use the CPU consumption level curve, and thread drill-down against time. 我通常使用CPU消耗水平曲线，并随时间深入分析线程。

but recently I am suspecting that yourkit is causing the random 20-seconds freeze in my application, since no excessive IO or GC is happening, and in such freeze period, the machine's CPU utilization drops down to about 5%, so it's not doing busy GC. 但是最近我怀疑您的套件在我的应用程序中导致了20秒的随机冻结，因为没有发生过多的IO或GC，并且在这种冻结期间，计算机的CPU使用率下降到了5％左右，因此它并不忙GC。

so I'd like a tool similar to yourkit, to try it out , to see if the issue is really due to yourkit 所以我想要一个类似于yourkit的工具，尝试一下，看看问题是否真的是由于yourkit造成的

the following shows one freeze, you can see that the CPU usage is a straight line for the center period, that's because yourkit wasn't able to take samples during that period, in fact for that period JVM was frozen. 下面显示了一个冻结状态，您可以看到中心时段的CPU使用率是一条直线，这是因为在该期间，您的套件无法采样，实际上是在此期间JVM冻结了。

I checked that there is no stop-the-world GC in that period 我检查了那段时间没有世界各地的GC

thanks a lot Yang 非常感谢杨

VisualVm具有yourkit的某些功能。

You can try JProfiler (disclaimer: my company develops JProfiler). 您可以尝试JProfiler （免责声明：我公司开发JProfiler）。 VisualVM has some basic profiling capabilities, but feature-wise it does not really compare to Yourkit or JProfiler. VisualVM具有一些基本的性能分析功能，但从功能上讲，它实际上无法与Yourkit或JProfiler相比。
