several hundred thousand to a milion or more key value pairs

How big are the keys and values on average? And how big are the xml files on average?

I am working on a blade server with 24 physical CPU's and more than 500gb of RAM

Is the blade server set up as a single SMP system? How many cores/threads per cpu?

Given those resources and requirements...what are your thoughts?

I'd want to see the answers to the above questions before reaching any conclusions about how I would go about tackling the problem.

Sight (public or private) of a typical example of the XML input and the keys/value pairs derived from it would help.

In the absence of evidence, opinion is indistinguishable from prejudice.
