Are there any scientific papers about any study performed on what is considered a maximum waiting time for an activity to be considered "user real-time" (not software real-time).

I was looking at something along the lines of "maximum waiting time for a web page to render" and the user's perception of real-time.

For instance empirically, we can state that waiting 200 ms would be real-time whereas waiting 10 seconds would not, but I was hoping to find some citation for it in scientific literature.

I've tried some resources (eg Google Scholar) but to no avail.

Thank you.

In Chapter 3 of Designing and Engineering Time by S.Seow there are list of standards which consern time and user experience. In average, "user real-time" response is in interval of 0.2-1.0 sec.
