Javascript is executed on the client browser, if it takes long time to
execute, then the surfer should get a faster computer.

If you would flush() the things in two parts, then you will only delay the
time before the client gets the javascript and then they have to wait as long
as now with that the javascript will be executed.

<?PHP
ob_start();
echo "html";
flush();
echo "javascript";
ob_end_flush();
/* at this stage the javascript will begun to be executed */
/* so the long wait will start now - better not save any */
/* thing in the buffer and let everything go out at once */
?>
