usage of mod_gzip is quite small nowadays and I don't think it's the problem
but the flushing of the output buffer in php.
Use ob_flush() to get out the data you want
<?php
/* header stuff and such */
....
/* head of HTML */
....
/* div for the waiting message */
....
/* javascript to enable div */
....
ob_flush();
/* do what you need to do with the mysql */
....
/* generate the rest of the page */
....
ob_end_flush();
?>
That could work for you, but I won't guarantee it will.
