Well, it's not that hard to understand. It takes time for the page to
get sent to the client. Generally it's a lot longer than the time it
takes to retrieve data from the database. A query might take 100
millisec. Transferring a HTML page could conceivably take over 10
seconds. Holding onto the connection til the end of the page means
more concurrent connection there needs to be.
