Support for huge teams: increase the timeout and run the fetch asynchronously?

[damienalexandre]

We often get reports of timeout during the "fetch user" phase, in this phase we paginate the whole team user list.

This can be very slow/huge.

When this happens, we trigger an error if it took more than 19 seconds.

if ((time() - $startTime) > 19) {

On the hosting we have a 3 min timeout so a quick fix is to change this wait time.

Another fix is to display a real page and load the users asynchronously via Ajax calls to improve the user feedback.
