But, again we should look at the big picture.  The apps will get faster, but
at what price?  More CPU/Processing used as a whole?  Which means that the
more hits, the performance gets worse faster.  This will also affect the
efficiency of other applications and procedures on the machine.  

I'm running (well, I shut it off) WAS 3.5.2 and it takes 5 minutes to start
it up.  For that 5 minutes, it's using 98% CPU.  That's unacceptable.  I
hope it gets better, or I hope IBM implements a way to use Tomcat or another
servlet engine as an integrated part of my AS/400 web server.
