I have cable connection but forum pages still feels heavy and laggy. Some post-"view source"-ing idea: Forumjump menu <div class="vbmenu_popup" id="navbar_forumjump_menu" ... Code (markup): (quite big piece of code) can be moved to external "forumjump-NNN.js", so it can be cached by browser. Js can be optimised for faster rendering. pro: smaller page, less traffic
It wouldn't save a whole lot. The forum uses gzip compression, so something that is say 1k in size, really only has to transfer about 200 bytes. Also, the forum jump menu can't be embedded in JavaScript because it's not the same for all users.
