Joe, while performance is critical, I think your statement needs to be 
expanded upon.  Consider the WRKACTJOB command, which gives you a view 
of a system where hundreds or even thousands of jobs are active, and 
where there are actually even hundreds and thousands of other processes 
going on under the covers.  The task dispatching and workload managment 
capabilities of the OS are incomparable in the industry.
If I had to name only one magic bullet, it would be the Native Virtual 
Machine.  Any other platform in the world can scale by adding a physical 
tier in front of, or along side another server.  But I'd much rather add 
another processor to a single server and let the native virtual machine 
manage the workload than monkey with another physical tier.
I understand that J2EE hosting environments offer some workload 
management capabilities, and so does an environment like PHP (if you buy 
Zend add-ons), and so does PASE, but they pale in comparison to what's 
offered under the native virtual machine.
