#38825 [NEW]: including a file is slower than expected
From: mark dot pearson at capita dot co dot uk
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:

The include process is identical on all Win32 systems, any
slowdowns are likely to be related to either the drive speed
or the OS internals.
That said one of the reasons you are getting such bad
numbers is because you are using a partial path PHP needs to
resolve first. This compounded with ZTS mode makes things
very slow, change the include statement to use full paths
and you'll see much improved performance, not to mention
much more consistent numbers.

I changed the path in my benchmark script to say both:
include './emptyfile.php';
and
include 'C:/www/php5tests/emptyfile.php';
and it made no difference whatsoever to the performance of the script,
contrary to what was suggested.

I changed the path in my benchmark script to say both:
include './emptyfile.php';
and
include 'C:/www/php5tests/emptyfile.php';
and it made no difference whatsoever to the performance of the script,
contrary to what was suggested.

The include process is identical on all Win32 systems, any
slowdowns are likely to be related to either the drive speed
or the OS internals.
That said one of the reasons you are getting such bad
numbers is because you are using a partial path PHP needs to
resolve first. This compounded with ZTS mode makes things
very slow, change the include statement to use full paths
and you'll see much improved performance, not to mention
much more consistent numbers.

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:

Running the benchmark script again on Platform 2 (Windows Server 2003
Xeon 2.80GHz processor) and the latest PHP5.2 snapshot gives the
following results:
D:\www\php5tests>D:\php5.2\php.exe -n benchmark.php
Elapsed time: 1.3624229431152
D:\www\php5tests>D:\php5.2\php.exe -n benchmark.php

D:\www\php5tests>D:\php5.2\php.exe -n benchmark.php
Elapsed time: 1.3796901702881
This still seems slow given that the same benchmark script gives an
average execution time of 0.52 seconds on Platform 1 (Windows XP
laptop) with the same PHP5.2 snapshot.

Reported By: mark dot pearson at capita dot co dot uk
-Status: Open
+Status: Feedback
Bug Type: Performance problem
Operating System: Windows Server 2003
PHP Version: 5.1.6

Please try using this CVS snapshot:
[url]http://snaps.php.net/php5.2-latest.tar.gz[/url]
For Windows:
[url]http://snaps.php.net/win32/php5.2-win32-latest.zip[/url]
There are a few more Win32 related patches in the code now
that should improve the speed of the file system operations.
Can you give the latest code a try.

Running the benchmark script again on Platform 2 (Windows Server 2003
Xeon 2.80GHz processor) and the latest PHP5.2 snapshot gives the
following results:
D:\www\php5tests>D:\php5.2\php.exe -n benchmark.php
Elapsed time: 1.3624229431152
D:\www\php5tests>D:\php5.2\php.exe -n benchmark.php
Elapsed time: 1.338228225708
D:\www\php5tests>D:\php5.2\php.exe -n benchmark.php
Elapsed time: 1.3370630741119
D:\www\php5tests>D:\php5.2\php.exe -n benchmark.php
Elapsed time: 1.3375468254089
D:\www\php5tests>D:\php5.2\php.exe -n benchmark.php
Elapsed time: 1.3394939899445
D:\www\php5tests>D:\php5.2\php.exe -n benchmark.php
Elapsed time: 1.3721809387207
D:\www\php5tests>D:\php5.2\php.exe -n benchmark.php
Elapsed time: 1.3796901702881
This still seems slow given that the same benchmark script gives an
average execution time of 0.52 seconds on Platform 1 (Windows XP
laptop) with the same PHP5.2 snapshot.

I changed the path in my benchmark script to say both:
include './emptyfile.php';
and
include 'C:/www/php5tests/emptyfile.php';
and it made no difference whatsoever to the performance of the script,
contrary to what was suggested.

The include process is identical on all Win32 systems, any
slowdowns are likely to be related to either the drive speed
or the OS internals.
That said one of the reasons you are getting such bad
numbers is because you are using a partial path PHP needs to
resolve first. This compounded with ZTS mode makes things
very slow, change the include statement to use full paths
and you'll see much improved performance, not to mention
much more consistent numbers.
