Apache different RES memory
 
Hi,

I am comparing two Apache installation on two different Debian server.
Both are Debian Squeeze, but one have 64bit cpu (and OS), the other is 32bit.
Both are using Apache's deb package, prefork, with lib-apache-modphp5.
If I do some tests and look at "top" command, I see that:

- 64bit os: the apache average RES size memory is 40M
- 32bit os: the apache average RES size memory is 12M

both are sharing the same configuration file and the same loaded modules.
How it's possible?
Thankyou

I don't understand.
Using 64bit operating system implies necessarily higher ram consumption for applications?

No, it implies a completely different architecture for dealing with memory.
