From the *same* browser?

Cuz, like, some browsers only allow one connection at a time, others limit
it to 4, some let you configure it, some don't...

Check your browser settings or try a different browser to access other
content while the first browser plugs away at the slow stuff.

You can also throw something like Apache Benchmark at your server to see
if the children are behaving. It should be pretty apparent if things are
out of whack with that, I should think.

Always seems to me like the same child will get used unless you actually
manage to get TWO requests through at the same time.

Presumably, this is more efficient, as it avoids having to page memory to
swap in another child.

Shouldn't matter, I don't think.
