How much database (size) is it suitable for local Meteor storage?

I've been using Meteor for a while now and totally in love with this framework. However, I have one curiosity.

Meteor stores one replica of the database in the local storage of the browser. But in some cases, for example to get user information on a website of about 100,000 users, it makes sense not to publish this collection and get this information directly from the server using your call / method functions.

So, I would like to understand how and where does the Meteor database store data in local storage? What is the maximum database I have to save before affecting the user's browser performance?

Thanks in advance for your answers.
