[geeklog-devel] Reducing the number of HTTP requests

[Niemans]

Some js-files are not exciting and should be discarded: common.js (only for Admin), confirm.js (what?), search.js (can be done in css).
Some others are useful and have an odd name. Group them all in one file called glUtilities.js.

Some blocks use images and the loading can de delayed.

Adding it up:

remove polls : save 2 requests
remove captcha: save 1 request
remove forum: save 2 requests
remove common.js: save 1 request
colate fix_html.js, confirm.js, search.js into utilities.js: save 2 requests

Total 8 requests saved.

Than use lazy-loading of images in blocks. Saves you > 10 requests on page load. Well, in the case Dirk showed.
