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

Hi Nathan,

I think language efficiency comes well down the list after the hardware 
- and I apologize if that was not clear from the article.

It does have an affect but nowhere near the affect it used to have. 
Henrik quoted the solution serving 400 web (companies) users - 10 jobs - 
running on a 520 (I am assuming RPG). I also get through a fairly heavy 
workload on my little 620. But I wonder what kind of response we would 
be getting running the same software on an old B20 (if it were possible)?

Performance is of course a consideration. And language can have a large 
part to play in that. But I think the application would really dictate 
how performance may be affected by the language - e.g. Java gives you 
multi threading, RPG gives you better database access, PHP gives you 
better session handling etc. etc. - as to which of these is most 
important depends on the application.

Language is about the right tool for the job. And the most important 
point about that is you have to know the language. No point saying Java 
is the right language if you can't program in Java.
