I got these three js on my forum and I am wondering, whether it is good to combine them as one and how to do it, effectively.
<script src="http://elkarte.sch.my/themes/default/scripts/jquery-1.11.1.min.js" id="jquery"></script>
<script src="http://elkarte.sch.my/themes/default/scripts/jquery-ui-1.10.4.min.js" id="jqueryui"></script>
<script src="http://elkarte.sch.my/cache/hive-e1788f8b777120fdeafe83580e4e3ed414f11e56.js?9f246aca" id="jscombinedtop"></script>
These three are already minified files.
The only thing you'd save combining them is 2 requests each page.
On the other hand, for the way minification is done, you'd have to serve a much bigger minified file different for most of the pages.
We decided not to include minified files in the minification process exactly for that reason. I don't think combine them would give you any advantage apart from some googlepagespeed-like test not telling you "you should combine all the js files to gain 0.05 KB". ;D
Thank you for the input.
As for the pagespeed, the test site already scored 92% on desktop and 79% while on mobile. So nothing much can be done for now except for a more user-friendly design in mobile view.
