Firefox (and most browsers for that matter) limit the

In Firefox, type in the URL,


Then look for these settings:


Of course you can use Graham's suggestion of using the
"ab" tool to really test things.

This may also be some browser limiting side-effect (of which I don't

Use ab, or even open lots of terminals/shell prompts, and use
wget in each one.
