Depends on the language.

No, it doesn't.

Perl e.g. has very powerful text operators, is interpreted, but is still one of the best ways to massage large text files (Perl regular expressions are NICE).

But correctly written C code that does the same thing will run much faster.

(and I don't think I'll bite on why compiled Java is slow on the i ;-) )

Not sure what you mean here. Are you saying that Java on the i is slower than Java on a Windows machine? That's got nothing to do with the issue. On the same platform, though, I disagree: Java code compiled by the JIT compiler runs faster than the same Java code interpreted - on any machine, including the i.

Now, if you mean using the CRTJVAPGM compared to the JIT compiler, that's a different question. CRTJVAPGM (which AFAIK is no longer recommended) does static optimization which can't compete with the dynamic optimizations of a good JIT compiler. If you want to learn more, start with Wikipedia:

I don't pretend to be an expert. Optimization is a class of programming way above my expertise. If you want to talk about people who really know how a computer works, the optimization folks are the very best in the business.
