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

[Aaron Bartell <aaronbartell@xxxxxxxxx>]

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?
