Subject: php5 uses cca 33% more memory than php5 package running on other systems

Date: Wed, 05 Oct 2011 21:40:51 +0200

Package: php5
Severity: normal
Tags: squeeze sid

Hi,

I was testing a simple script for memory usage and I found out that debian is using circa 33% more memory than other systems. This means that running huge php software (like magento) is painful under debian.

The testing files are:
http://srnka.info/download/php5-test/adding.txt
http://srnka.info/download/php5-test/vartest.txt

Please, rename them to .php and run vartest.php.

Here are results running the scripts on various systems (all of them are 64bitssystems):
CentOS 6: Time 0.069308042526245<br/>Memory: 14.61 MB
MacOS X 10.6: Time 0.073976039886475<br/>Memory: 14.61 MB
Ubuntu 11.04: Time 0.066581010818481<br/>Memory: 11.28 MB

Debian Wheezy: Time 0.065372943878174<br/>Memory: 21.97 MB

I tried to use Ubuntu's (11.04) php runtime under Debian, however the results are the same as for Debian, so this bug might not be directly inside PHP package.

Hi,

this bug got probably fixed when we disabled suhosin from the package.  Could you retest with
php5 in sid (>= 5.4.0)?
