Re: Which scales better? J2EE, PHP, or CGIDEV2?

What's interesting to me is that it almost seems that scalability has
nothing to do with how well something performs but rather how well it
can progress to use more resources! LOL!

So if RPG output a string of "HelloWorld" in 1 msecond and Java did it
in 2 mseconds, we aren't necessarily considering that RPG is more
scalable - just that it can accomplish a particular task faster.
Though that may mean the point in time we need to scale is later using
RPG and sooner with Java - so in a way the language (or rather the
language runtime) *could* be a scalability issue.

Thoughts?

Maybe we should define scalability.

The Wikipedia definition works for me. "scalability is a desirable property of a
system, a network, or a process, which indicates its ability to either handle
growing amounts of work in a graceful manner or to be enlarged."

Under that definition CGIDEV2 would scale well just by running under IBM i where
available resources (processors, memory, etc.) are automatically allocated to
separate jobs.  No need to configure anything, except standard HTTP server
configuration directives allowing a given number of threads and CGI server jobs,
timeouts, and so forth.  Native workloads automatically scale to use available
resources.

Is the same true for J2EE and PHP?
