Aaron,

as long as you keep scalability within a 128 concurrent RISC processors
range and one DB,
I dont think you have a scalability problem

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?
