yeah, possibly. This is old reasearch [1] with oldish minifiers (e.g. no UglifyJS) and only one script - jQuery from 5 years ago. However I don't expect large discrepancies if the reseasrch is duplicated with new modifiers and larger sample. What would be more interesting is to see the results of the different minifications. E.g. how much you get from simply removing comments and whitespace? How much if you also rename variables? There might be diminishing returns (and increased security risks) if you go further than those two simple and "safe" improvements [1] http://www.phpied.com/reducing-tpayload/ http://www.phpied.com/reducing-tpayload/
