Eh, even on this example, most of the gains come from simply removing the comments (something that can easily be done with `cpp -E -P <in.css >out_cpp.css` or regexps since CSS doesn't allow comment nesting) on most UNIXes. Here's a more complete result adding brotli and the aforementioned cpp version: $ gdu -b *.css *.css.gz *.css.br | awk '{if (NR % 3 == 1) {ref = $1; print} else print $0, "(" $1 - ref ")"}' 623 in.css 197 out.css (-426) 355 out_cpp.css (-268) 345 in.css.gz 185 out.css.gz (-160) 235 out_cpp.css.gz (-110) 284 in.css.br 141 out.css.br (-143) 177 out_cpp.css.br (-107)
