Operating system: Windows Server 2003
PHP version: 5.1.6
PHP Bug Type: Performance problem
Bug description: including a file is slower than expected
Description:
------------
Having recently set up a Windows Server 2003 web development server it has
been found that file access by way of PHP 'include' is much slower than it
should be when compared to other platforms.
A small benchmark script (included) was run on four different platforms
(none of them production servers), using both PHP4 and PHP5 as described
below:
PLATFORM 1
----------
System:
Microsoft Windows XP
Professional
Version 2002
Service Pack 2
Computer:
Intel(R) Pentium(R) M processor 1600MHz
589 MHz, 512 MB of RAM
PHP versions tested:
4.4.4 and 5.2 2006-09-13 snapshot
PLATFORM 2
----------
System:
Microsoft Windows Server 2003
Enterprise Edition
Service Pack 1
Computer:
Intel(R) Xeon(TM) CPU 2.80GHz
2.80Ghz, 2.00GB of RAM
Physical Address Extension
PHP versions tested:
4.4.4 and 5.2 2006-09-13 snapshot
PLATFORM 3
----------
System:
Microsoft Windows Server 2003
Standard Edition
Service Pack 1
Computer:
Intel(R) Xeon(TM) CPU 3.00GHz
3.00Ghz, 3.50GB of RAM
PHP versions tested:
4.4.4 and 5.1.6
PLATFORM 4
----------
Fedora Core 4
Pentium 3 760MHz
256MB of RAM
4.3.11
The benchmark script was run 6 times on each platform.
Reproduce code:
---------------
benchmark.php
-------------
<?php
$tmp = split(" ",microtime());
$start = $tmp[0] + $tmp[1];
for ($i = 0; $i < 5000; $i++){
include 'emptyfile.php';
}
$tmp = split(" ",microtime());
$end = $tmp[0] + $tmp[1];
print "Elapsed time: " . ($end - $start) . "\n";
?>
emptyfile.php
-------------
<?php ?>
Expected result:
----------------
I would expect the benchmark.php script to run more quickly on both
PLATFORM 2 and PLATFORM 3 (both of which are high spec servers running
Windows 2003 Server) than on PLATFORM 1 (a Compaq nx7010 laptop running
Windows XP Pro) or PLATFORM 4 (a Dell Optiplex GX110 running Fedora Core
4).
Actual result:
--------------
The script completed more quickly even on PLATFORM 4 (Pentium 3 730MHz
256MB RAM) than on PLATFORM 2 and 3
The results are included below:
