High memory usage
Hi, first of all thank you for this package 🙏🏼
I've noticed that my service at production env get's restarted due to high memory usage.
I've debugged it, and looks like proto.js is 17% of my entire app memory usage!

There is anything we can do in order to improve it? Maybe it is better to split this file into separate "domain" based files?
I have the same issue as described here. Would be great with some kind of resolution as it both takes a long time to load on cold start and it just eats a whole bunch of memory.
