[UPHPU] script timers

[Daniel]

There is serious latency from the time someone pushes a button on our
webpages and the time the following page is displayed.  I would like
to know how to pin point the bottle neck.  We date stamped the second
page at the beginning of the script and at the end and subtracted the
two times to get a sub-second period.  For some reason the page takes
a few seconds to come up.  Where could there be a bottle neck and how
can we find out exactly where it is?
