Was your client sending the requests concurrently? If I do that and run "ab -n 100 -c 100" (for 100 requests run with concurrency 100) the benchmark takes almost exactly 2 seconds to execute all 100 requests.

I guess not - it worked when I followed your suggestion. Thanks!

I was naively cranking out a bunch of tabs in Firefox really quickly. :) I guess Firefox doesn't make concurrent requests when it's the same URL...?

Firefox only makes two (by now maybe four) concurrent requests to the same server as mandated by the HTTP protocol.

It's technically not mandated, but recommended. Servers need to be able to deal with more anyway, as proxy servers are recommended to open up to 2 * [no of clients] connections to upstream servers.

Firefox has a maximum of 2 connections per host - though it's being upped to 6 in Firefox 3.5.
