Hi all,

Just installed my first server for real - an amd64 X2 AM2 3000+, which will
be going into production soon.

I am concerned about memory use, are the combined -xen kernel not using more
memory than an optimized? What is the overhead by using the universal module
kernel compared to compile a static kernel with all needed parts compiled
directly in?

Thank you very much in advance, for you comments.
