Calculate when a browser can slowing down [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 12 years ago.

Is it possible to calculate within a reasonable approximation, how many tabs a browser can open before the system slows down, according to the components of a computer (ram, cpu, video card etc..), to the average thickness of the currently opened web pages, active processes, and system-wide machine usage (i.e. memory, cpu)?

A possibile use case could be to show a user, which pages are using more res开发者_如何转开发ources than others so she could easily optimize the performances.

No.

But I'll confess its not as stupid a request as it sounds.
