plz test again with latest CVS version. it should be a lot better now.
my system (gentoo linux) shows much better performance, so i'd want
some feedback.
btw: my system runs the script at about 0.74s (almost constant)
thanks!

I installed PHP5RC1 on my WindowsXP so that I can have a look at my oo
php4 app and see what I would have to change with PHP5.
Unfortunatly with this PHP5, my require_once() calls at the beginning
of my scripts become by far the performance bottleneck. Where any page
of the app used to take an average 0.2s it now takes about 1.5s, mostly
due to require_once() calls.
I can't think of migrating because of this. Well, i'm sure it will all
be fixed soon :)
Keep up the good work.

I have the same problem with the version : 5CVS-2004-04-24 (dev)
Includes are very slow...

The same thing on PHP5/Windows XP SP1.
I think there's nothing to add to the things said above.
PHP5 simply parses code too slow.
The bug is extremely easy to reproduce – I’ve tried with different
configurations and on different Apache/platform combinations – but it
still there.
You take any class put it to separate file then include it from another
one and measure the time taken by include. The difference between php4
and php5 is up to 15-20 times.

Some more data points. I used apache bench to run the test.php script
in my last post. I tested against php 4.3.2 and today's cvs php5.
Here are the results.

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";
?>
