ok with further testing, I have trimmed my configure line down to the
following.
./configure \
-with-apxs=/usr/local/apache/bin/apxs
I then restart apache.
First hit to the test script .097 s
Second hit .187 s
third .264 s
.332 s
.346 s
.392 s (peaked out here)
In each test, I wait a few seconds to make sure there is no load on the
machine. I'm using a seperate machine to run the browser as to not
polute the server response times.
The entire php script.
<?php
$_time = explode(" ",microtime());
$start = $_time[1] + $_time[0];
$phphtmllib = "phphtmllib";
include_once( $phphtmllib."/includes.inc");
$_time = explode(" ", microtime());
$stop = $_time[1] + $_time[0];
$elapsed = substr($stop - $start, 0, 5);
echo "<i>elapsed time: ".$elapsed." s </i><br>\n";
?>

finally bugs.php.net is accessable again. I wasn't able to hit it
since last friday! bleh.
Anyway, I have tested w/ an up to date (as of now) cvs tree of php-src
and have re-run the test and am still seeing significant slowdowns just
by doing includes.
I am running the sample script that I have listed in the original
post.
php4 = .075 ms
php5 = .372 ms
php5 is acting strangely. I do a restart of apache.
First time I hit the test script (php5) I get a time of about .100ms.
I then wait about 2 seconds and make sure there is no load on the box.
Then I hit reload in the browser. That takes .237ms. I do the same
thing again, and the next time the script takes even longer to execute
at .372ms.
Here is my configure line.
./configure \
--with-oci8=/u01/app/oracle/product/8.1.7 \
--enable-sigchild \
--with-mcrypt \
--with-gd \
--with-png-dir=/usr \
--with-jpeg-dir=/usr \
--with-zlib-dir=/usr \

--enable-sysvshm \

--with-mysql=/usr \
--enable-mbstring \

Can't you test this with some other code which doesn't require bug
#27227 to be fixed..?

Then we leave the status at "Feedback" until you can test again.

I can't really test this right now because I am waiting on another php5
bug to get fixed. The other bug is
http://bugs.php.net/bug.php?id=27227 related to
a bug in mixed case in
constructor names not being called correctly.
