This is a poor question. You are asking a for a lot but providing little. The answer, at the same time, can be yes and no.
You leave out critical information, such as what the scaling is for. Is it to support lots of users or lots of computation? Lots of concurrent connections? Are you talking about meteor.js alone, or are you looking at other technologies? And what is high performance to you? What is a large code base? Why do you presume it will require a large code base?
You provide no requirements, and the question is purely subjective.
But pc86 makes a good point: it probably doesn't matter at this point. With the information you provided, that's the best answer anyone can give.

tl;dr: Yes and no.
