A few years ago I read a PDF from an IBM Web site.  It delineated a 
performance analysis of WAS under a stress test.  They initially 
couldn't drive CPU usage past about 60% no matter how many threads they 
configured their application server instance to run.  They later loaded 
multiple instances of WAS and used a load balancer between each 
instance, which finally did drive CPU to 100%.  I seem to recall that 
ZEND supports something comparable to multiple application server 
instances, but I don't recall if it's a separate product or how to 
configure it.

This bit of trivia may not even be useful.  Were you expecting PHP to 
perform as well as RPG CGI?
