Re: CGI programming

I always design for maximum performance, to a point. Our as/400 is all SSD drives, and very fast for the 150 users, so if I have to spend hours (or days) if making it that much more efficient given the hardware it runs in and users affected all for milliseconds of improvement, I probably won’t spend the time.

It’s all relative imho.

I don't think people dismiss runtime speed, but it must be weighed against the cost of developer speed.

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.
