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:

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 Squeeze: Time 0.075584888458252<br/>Memory: 21.98 MB
Gentoo: Time 0.11691498756409<br/>Memory: 14.62 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.
