Tests were measured using a Firefox plugin called Firebug. Firefox was run a Mac Pro (2008) using OS X 10.5.3. Eight files were included in this test: builder.js, controls.js, dragdrop.js, effects.js, prototype.js, scriptaculous.js, slider.js and sound.js - all taken from the script.aculo.us website.
The default behaviour is to specify one file for WP JS to JSMIN and GZIP.
However it is also possible to combine several files together. It is very easy and only requires that you comma separate files inside the string parameter.
