Technically correct.  But CGI programs run under the IBM i native virtual 
machine, Servlets run under a web application server, which runs under a java 
virtual machine, which runs under a native virtual machine, and PHP scripts run 
under an interpretive runtime environment, which is essentially a virtual 
machine too.  

When we discuss scalability, aren't we really discussing the ability of the 
virtual machines to handle increasing workloads?  It seems that in that context, 
efficient languages enable their virtual machines to handle increasing 
workloads.
