起因之前 TMS 在运行时 CPU 中占用率和内存占用一直很高，导致应用运行状态不是很良好，需要频繁重启。经过排查，找出了部分原因：使用的 html-minifier 模块有问题，如果输入的内容是一个有错误的 HTML 结构，会使解析进入死循环，导致 CPU 占用率 100%。在使用 vm 模块时，使用姿势错误，导致内存占用无法释放，使内存占用暴涨。第一个问题我们今天不予讨论...

Node.js 应用故障排查手册 —— 利用 CPU 分析调优吞吐量

楔子在我们想要新上线一个 Node.js 应用之前，尤其是技术栈切换的第一个 Node.js 应用，由于担心其在线上的吞吐量表现，肯定会想要进行性能压测，以便对其在当前的集群规模下能抗住多少流量有一个预估。本案例实际上正是在这样的一个场景下，我们想要上线 Node.js 技术栈来做前后端分离，那么刨开后端服务的响应 QPS，纯使用 Node.js 进行的模板渲染能有怎么样的表现，这是大家非常关....
