Obviously authorisation will be a huge overhead compared to sendfile + nginx right? Am I misunderstanding what npm does?

I mean, to use sendfile you need to open the file, and that does a permission check too...

No I'm talking about private NPM right. The perms on the file system are not equal to (or as costly as) the auth I need to have to access my private NPM repo.
