Hi, you can set a config option to tell OpenGoo to try to gzip-compress javascript, but this may not work an all servers and browsers. This will speed up the initial loading times. To try it edit config/config.php and add a config option called 'USE_JS_CACHE' with a value of true. If it doesn't work just delete it and all should be back to normal.
Also, from version 1.1 onwards, we will include with the download compressed versions of javascript and CSS. This should improve initial loading times even more.
Cheers.
