Answer 1

The max concurrent connections should depends on your hardware. This article said node.js can support tens of thousands of concurrent connection. However, most linux systems only allow you open 1024 files/sockets on same time by default. For that case, you can run as root and then set ulimit as a big number(e.g., 100000), then run a stress test with your hardware for getting the accurate capacity of concurrent connection.
