You weren't

the actual speed test to give a valid result.)

I wrote back to Paul about his correction to use "foreground" instead of
"focus".

I only want to correct what you said which is that if all you do is
open a
single browser session which has two tabs, one of which is blank, I don't
think switching the "foreground" from the speedtest tab to the blank tab
"should" have any impact on the speed test.

True, if that's _all_ you do. The usual reason for opening more tabs,
however, is to load more pages (-:

Why would just switching the speedtest tab to "background" mode have any
"real" impact on the speedtest results?

The impact would be that "advertising" or some other thing wouldn't
happen
if you didn't watch the paint dry on the speedtest (where the
speedtest is
just an easy example that happens to be fast).

A proof of that is I can break the two-tab browser into two separate tabs

ITYM Windows (-:

both of which are now by definition in "foreground" mode, and then the
speedtest runs to completion.

Speed tests do NOT give correct results when you are running something
else on the 'net.
