I would like to address this one as part of performance work. We have existing bug for this, but I'm sending also this to list to get wider feedback. http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=1918 I found https://github.com/jshirley/Plack-Middleware-ComboLoader which got me pushed in right direction, but in the end I decided to implement Koha::Template::Plugin::Combine because it turned out that it's easier if we can use combining and minification together. Changes are available at: https://github.com/dpavlin/Koha/compare/dpavlin:plack...dpavlin:bug_1918-com... Minification alone doesn't buy us much: OPAC search: minify js 334974 -> 311553 93.01% minify css 148277 -> 133128 89.78% intranet search: minify js 382102 -> 362172 94.78% minify css 134754 -> 123771 91.85% But combining JS and CSS files together saves us round-trips to server: OPAC 32 -> 20 requests intranet 27 -> 13 requests I would love to hear your feedback on this. -- Dobrica Pavlinusic 2share!2flame dpavlin@rot13.org Unix addict.
