有多少用户 Nodejs &Socket.io可以支持吗? [英] How many users Nodejs & Socket.io can support?

问题描述

我有一个实现了broadcast.emit 的网站.向网站的所有用户发送消息.它只是 socket.io 的最简单实现，但我目前遇到了问题.当我达到大约 100 个并发用户时.nodejs 服务器开始滞后，直到它挂起，我无法再访问我的整个网站.当我们检查服务器时.nodejs 占用了 100% 的 CPU.正常吗?

I got a website that implements the broadcast.emit. that sends message to all users of the site. It is just the simplest implementation of socket.io but I currently having a problem. When I hit about 100 concurrent users. The nodejs server starts to lag until it hangs that I can no longer access my whole website. When we checked the server. The nodejs is taking 100% of the CPU. Is it normal?

我想知道 socket.io 可以支持多少用户?当这件事发生时，有没有办法以编程方式重新启动 nodejs 服务器?

I was wondering how many users can socket.io supports? And when this thing happen is there a way to restart the nodejs server programatically?

推荐答案

至少 250k 个并发连接(对于大多数用例瓶颈是内存)

At least 250k concurrent connections (and for most use cases bottleneck is memory)
