Unless your machines are *very* slow, this should not be true.

I've supported over 100 users on a single Sun SS5 before, on a very fast
net connection.

Even images and static content used in websites you commonly visit?

I don't see your point.  Opening up several windows is effectively
downloading in the background too.

Using tabs should use less memory.

In any case, none of it explains the problem.

I don't follow your logic.  The browser always does background fetching.
You cannot turn that off.

The background option in the configuration dialog only controls wether
or not you are switched to the new tab you just opened.

It has nothing to do with background fetching.
