Is there a ratio or some formula for a initial heap configuration agaist the CPU / memory the JVM is going to run on?

Welcome to the JavaRanch, John!
I haven't checked recently, but last time I looked,
ran using default JVM memory settings. Which for the Sun JVM was 128MB. I recommend starting with 256MB in most cases, though.
The standard memory management rules are sufficient except for PermGen space, which may need to be overridden if you are working with ORM-based apps such as Hibernate.
Customer surveys are for companies who didn't pay proper attention to begin with.
