Why do people treat this as such a discovery? Where did Node claim to be the fastest solution to everything?
The only answer I can think of is that people feel threatened by node.js for some reason, and constantly feel the need to criticize it for not being the best at everything.
If you want to serve a 1mb file a million times, without caching it, or using sendfile, yeah, node will probably be slower compared to other things. It gets really old seeing posts like these.
