You won’t get many stars with marketing like “We are not the fastest but we are pretty efficient, no wait, we are actually not that fast”. It has to be something like “FEATURING THE FASTEST AND MOST RELIABLE REAL-TIME ENGINE”. Yeah, that one will sell. In fact, this is the marketing of Socket.IO, a project with 28k stars.
Node 09 年刚出现的时候被大吹特吹，被贴上异步事件驱动，高并发等标签，入门门槛极低，大量前端都可以跳到 Node写一下。一些无高质量的基础库涌现，库作者会吹 B，而且前端的人很多，这些库 star 数飙升，例如 Socket.io。但是到现在出现了性能低，无人维护等现象。
