In php there can be some interactions with output buffering so sometimes you need to use ob_flush() but if you're running Joomla you might want to avoid that - there could be code in the templates that are counting on the buffers not having been flushed.

What version of Joomla are you running? Have you enabled the built-in page caching mechanisms? Joomla is one of the harder CMS systems to optimize because there aren't a lot of plugins that can help (though there are a few threads around here from people working on it).
