Speed Difference

I am using PHP4 on NT 4 Server SP5 with Apache latest release (1.3.2?). The machine has 64 MB RAM and a P2-266. I have a document to serve that is a little complex, has a few embedded tables, minimal graphics, etc. Served as HTML, it's fast enough...on a LAN, less than 2 seconds...make that almost less than 1 second... Served as a PHP document, with an include for the header and footer, its slow, like about 5 seconds. That's a loooong time to wait for a simple web page. On these pages, aside from the includes, there is no other php code. While I know PHP4 is new, and windows is hardly the best platform for it, I'm wondering if this speed difference is normal, just a result of the sort-of-complex html, or a factor that the machine is "slow" from lack of memory etc. It might be the latter, because it is NT and not a smaller OS like Linux, but I would expect that 64 MB and a P2 would be able to serve web pages pretty quickly. If you want, view source on http://wendy.engr.ucdavis.edu/chms/safety.php Then compare that with http://wendy.engr.ucdavis.edu/chms/safety.php I have a page which accesses an ODBC DB, http://wendy.engr.ucdavis.edu/chms/directory.php and the html version http://wendy.engr.ucdavis.edu/chms/directory.html Thanks for any hints...
