Please, not again..... haven't we many times hashed over why Java is not in practice "interpreted". For most things, its performance is not that far from "C". When "Java" is slow, its almost always due to poor design (and programmers). Have you looked at the machine code generated by the Java JVM? Its great stuff, and automatically recompiles "hot" method stacks with fancy inlining, loop unwinding, etc as your program runs. Assembler programs are faster because assembler programmers are generally better, and they don't haphazardly pull in huge frameworks into their code without understanding the performance implications. Not so for your average Java programmer :-)
I can't speak for Carolina, but IMO the general design of compiling SAS code into Java byte codes (which are dynamically compiled into machine code) is not inherently flawed. This has been proven to be successful (and performant) over and over again for many languages that compile to Java byte codes. One would have to benchmark specific workloads with this technology to see how well it performs. It could suck, but it could also perform well.
