To add more data to this discussion, I've been playing with the GitHub Issues API recently, which pretty-prints by default. I grabbed the last hundred open issues from the Mozilla Persona repo, and found == Uncompressed == Pretty Printed: 312,556 bytes Minified: 272,604 bytes ------------- Delta: 39,952 bytes (+14.66%) Not as bad as a 24% hit, but that's all moot because gfodor very explicitly discussed using gzip when pretty-printing. Let's see what happens there: == Gzipped == Pretty Printed: 41,748 bytes Minified: 40,648 bytes ------------- Delta: 1,100 bytes (+2.71%) Not as good as the original claim of <1%, but still pretty darn negligible.
