Description

I ran into a problem where performance dropped dramatically when I switched on two strategies.These two policies subscribe to two kafka topics, respectively. I looked at processes that were using too much CPU, and found that the performance bottlenecks were in the spout send phase.The topics I subscribed to were divided into 10 sections, and the numOfSpoutTasks I configured was 20. How shall I adjust the performance problem?

我遇到了一个问题，在我开启了两个策略的时候，性能会急剧下降。这两个策略分别订阅两个kafka  topic,我查看了CPU使用过高的进程，发现性能瓶颈都是在spout发送这一环节。我订阅的topic分别有10个分区，我配置的numOfSpoutTasks是20.请问我要怎么调整这个性能问题。
