Calculating the disk size and memory usage is a big task and
there are many parameters the information depends on.

At least there are wiki entries (little bit older like this http://www.liferay.com/web/guest/community/wiki/-/wiki/Main/Frequently+Asked+Questions), the official liferay documentation and many forum posts that give
information about memory usage and so on.

I don´t think that there is one main guideline.

Important is also the load. If everything runs on one machine (also the db and the apache) you will need
a lot of memory and it will only work with a few people working with the instance.

For example if you use bundled tomcat 6 with java 6 you have to find the best working parameters:
Default settings:
--Xms128m (default) --Xmx512m (default) --XX:MaxPermSize=128m (recommended)

The system may become faster if you change the heap memory sizes:
--Xms1024m -Xmx2048m

But this also depends on your machine (64-bit?) and how vm share / use the memory.

Hope this helps,
J.

Hi Jenny,
Thank you for your help!

This is my first time that I work with Liferay.
I'm thinking to use :

Liferat 5.1 bundled tomcat 5.5 with JDK 5.


With this choice what version of MySQL is preferred to use?

Maybe the version of OS can be 64 bit, so I want to assign 4 GB for Liferay.

My problem now is to properly manage the disk size (etc) of my virtual machine: Vmware Server
where I have to install my Centos 5.3, Liferay and MySQL .

thanks!
