Thanks everyone, By default PHP does not do any output buffering. Apache buffers until it has a full TCP packet to send though. The PHP flush() call asks Apache nicely to flush this buffer, but you are better off avoiding this if you want to optimize your bandwidth. PHP 4 does have an output buffering feature that you can optionally turn on. -Rasmus
