Re: CGI programming

I'd add that most prepackaged tools used are on the client/presentation
layer (CSS and JS mainly), and available for any "tool" or language used.

John,

When people dismiss run-time performance concerns, I always image them
working on small-scale development for small-scale organizations. Is that a
valid assumption on my part, in regard to your last comment?

We recently developed an IBM i based student transportation system for a
public school district that hosts applications and data for 80K students,
parents, teachers, administrators, etc. They indicated that their student
information system (written in Java, which according to some benchmarks
performs better than PHP), requires a server farm of 20 systems, consisting
of something like 80 cores. If they were using our system (written in RPG),
I'd recommend a single 8-core Power server, which would save them a lot of
time that is required to manage their current server farm.

You keep alluding to PHP productivity, which I assume is in regard to the
phpGrid utility that you promote. But I wouldn't generally consider PHP to
be more productive than RPG, in most coding contexts.

Nathan.

I'm a big fan of using RPG for web apps - but my experience is that PHP
while somewhat slower is really not a performance issue. I doubt if it
takes even 1.5X let alone 20X - that's a crazy number. And that's without
doing any real tuning, buying the "boosted" Zend Server, etc. etc.

Where PHP scores is the easy availability of libraries which speeds up
development significantly. Same applies to Python and node and ...

Courtesy of PHP we have had new functionality available in hours rather
than the days or weeks it would have taken had we had to do it with RPG.
Sometimes trading off performance for speed and nimbleness of development
is the right trade to make.

Right tool - right job.

You are leaving a lot of margin. Using PHP will probably require 20 or
more cores to put up with the performance of 1 core ILE
