Required hardware

There are no built-in requirements. The hardware needed to run an eZ publish site depends on several factors, such as the average number of users, the size of the templates (including graphics), and how caching is used.
The installation requires about 50 MB on your harddisc. We do recommend some minimum values; at least 500 MHz CPU and 250 MB of RAM.
