I setup a simple benchmark test because I was curious how much
overhead parsing .html files as PHP files actually caused. Here are
those results:

The index.html test file is very simple:
<html>
<head>
<title>Benchmark Test</title>
</head>
<body bgcolor="white">
Benchmark Me!
</body>
</html>
Then the actual tests:
1) Apache not parsing .html files as PHP:

2) Apache parsing .html files as PHP:
(I edited /etc/apache/mime.types and added "html" to the
application/x-httpd-php line, and then I restarted Apache.)

The summary results:
For 10K local requests:
27.1 seconds with .html not parsed as PHP
vs.
30.2 seconds with .html parsed as PHP.
I only ran these tests locally, and only on the one server.. so it's
definatly not very scientific. I think we all sorta knew the results
anyway.
