 Ah. Fair enough.

 I'm suggesting that some of your code that is running after the header() call
that is taking a significant time.

 Adding exit immediately after header() prevents that code running.

 For a trivial example:

<?php
header("Location: http://www.php.net/");
sleep(10);
?>

 This takes 10 seconds to actually redirect. So the code that runs after
header() is significant. exit skips it. If it worked before, then surely it is
a possible cause that the code used to run quickly so you didn't notice, but
now it runs slowly.

 So, what is running after the header call?
