Difference between this.userId and Meteor.userId()?

This is my last reply on this topic!

Try to avoid called Meteor.user() on the server. It’ll fetch the user object from Mongo, everytime you invoke it.

On the Server Meteor.user() reads user data from Meteor.users collection.

ok, mine too)
And if it really causes some significant overhead, as you imply, it should be in the docs isn’t it?
