performance - 如何使用Mule中的线程工具解决如何解决性能问题？

转载作者：行者123 更新时间：2023-12-02 04:36:22

我正在使用Anypoint Studio 6.1和Mule 3.8.1，并且工作流程没有执行，因为线程监视看起来好像没有使用250个最大 Activity 线程，即使无限大的250个并发用户正在调用该流从JMeter 3.1开始循环。

我使用了VisualVM和YourKit之类的工具来调查问题并尝试确定解决方案。似乎大多数线程都已停放或正在等待，但是我不确定如何从线程转储和分析工具中找到最佳性能解决方案？

最佳答案

问题描述似乎不正确。您提到“看起来好像没有使用250个最大 Activity 线程”。那是问题吗？如果处理效率足够高，能够以比资源使用量少的资源使用量来回答所有请求，那为什么会成为问题呢？您需要澄清是否遇到与此相关的实际问题。

线程转储通常用于查找线程锁定问题，或在某些任务中线程明显延迟。对于性能问题，最好使用分析器，例如YourKit或VisualVM中较为有限的一种。同样，您需要更清楚地定义问题，以查看要使用的正确工具是什么。
