I think there was some really awesome benefits of nodejs that are worth mentioning. I recently finished migrating our old .NET API to NodeJS and found:

1) persistant connections, we deal with massive concurrency and remote connections to just about anything external (even on same network) could be saturated and overwhelmed so quickly

2) pseudo-caching data in the background, things like game configuration etc we just keep loading over and over on an interval so wherever possible we just have whole mongo collections and db tables sitting there in ram always fairly fresh

3) mirroring our application-wide redis cache locally on each server in the background so whenever we do get a cache hit it's insanely fast

These are probably the coolest things I found moving our analytics api to nodejs.
