I am working on a plattform that will have a lot of users in the so called "developing countries". So many of them will be using old computers and old browsers in tiny internet cafes.

We want to make sure to give them a good user Experience and make sure the website loads as fast as possible.

Problem is, that while you can save a lot of requeasts and time, using jQuery/AJAX, it also brings along a lot of Problems: - Will the Computers be powerfull enough to deal with the client side scripts? - Will the old Browsers handle jQuery?

Does anyone have any experience with these sort of problems or might know of some sort of article on the topic?
