Description

There must be something wrong in the SQL queries. When loading the page, even on a local install with only a few users and 3 courses, it loads in about 8 seconds...

Try http://chamilodev.beeznest.com/main/session/?session_id=1 as admin/admin. It takes about 7 seconds to load...

On a computer like mine, that's about 5000 000 million cycles, so it's veeery slow :-)
Anyway, I'm moving it to the next version but I'm pretty sure the problem is that, in order to get the JavaScript tabs, we are generating the whole contents of those page in one piece (all at once) with many statistics, live graphics, etc. This is most probably why it is slow.

Once we put that on http://campus.chamilo.org, it's going to kill the server, most probably.

Personally, I don't really mind having each tab loading separately (instead of having everything pre-loaded).

I need to analyse this one a big more. It seems to me like the slowliness hasn't been improved much, but I need to analyse it. On the other side, this might lead to more debugging because it seems to me like some (useful) graphics that were there previously now disappeared. In any case, it's not urgent, so I'm moving it to 1.10
