Javascript 分析节点的高cpu使用率（表示\uuuuuuuuuuuuuuu inc\u remove\u计数器）

我的测试设置（摩卡+卡玛）开始在空闲/观察模式下持续占用60%到70%的cpu。我像你一样运行它

NODE_ENV=test node_modules/.bin/karma start build/testing/karma.conf.js --no-single-run --auto-watch 

我今天从5.x->6.2升级了node，但到现在还没有高cpu（使用6小时后）。我按说明运行了个人资料。这些是日志

什么是移动计数器？？如何确定导致cpu高的原因

谢谢。

尽管我清除了ny

node\u moules

并重新安装了所有依赖项，但我仍然存在这个问题。它通过清除缓存

npm cache clean

然后重新安装所有dep来解决。
