64bit process - need help overcoming the downsides

Complementing the other question I have posted here 2 days ago (which no one seem to know how to answer concerning 32bit java process on intel64 Redhat) ... I wish to address my concerns regarding running my server as a 64bit process.

Apparently it takes 70% more memory to run it as such. Seems a low ROI to me to have x4 or so times the memory just to get x2 space.

Can someone direct me please to links or information regarding these issues and how to solve them (if a solution exists). Also concerning the wider more general issue of enterprise readiness of java 64bit processes nowadays

Thanks,

Woody.
