Thanks for the reply. You have me convinced with amortizing the cost of js over multiple visits rather than a single thread. Regarding the 4mb thing, I pulled it out of 1wd's comment. It would be best if 1wd came back and explained. That said, I believe the discrepancy is probably between the size of compressed javascript in the network and it's uncompressed size. Firefox dev tools show 3.1mb for meta.discourse.org. I don't know how to view the total size in Chrome's dev tools, but if you click the "use large request rows" in the Network tab you will see that application.js by itself takes up 1.5mb.
