<blockquote>There is clearly a negative correlation between file-size and the amount of filesize you save by minifying and gzipping compared to just gzipping. As an HTML document gets bigger minifying makes less of an impact. This is consistent with the way gzip works, the further the tokens from each other the less efficient the compression is.

Ultimately it looks like gzip eats html documents for breakfast whether you minify or not. I would say this is a self-confirmation of my original gut feeling: I would not trade minified html for even one minute of lost productivity due to some subtle bug introduced in the build process.</blockquote>
