Is anyone aware of any usability studies that address page load time
and impact to the users' experience and perception of a site? I'm
creating a page load service level agreement for a web app and would
like it if I had some research that reinforced my recommendation
(I'm recommending a 2 second maximum for the login process). If you
are aware of anything specific to homepages and login, that would be
even better.

I also would like this information, not just for login though. We
are trying to determine how long before a spinning wait indicator
appears for any action. Currently I'm also thinking about 2
seconds, but I would love to have something to back it up. Another
related question (not to hijack the original question), should a wait
indicator always be displayed for longer operations? Are there
operations, like when a new page is displayed, that shouldn't
display a wait indicator?
