The performance of binary computations, control flow, subroutine
calls, etc, will generally be much better in C, C++, or Java.
Decimal arithmetic and some operations that require intimate access
to DB files, etc, will normally be much faster with RPG. The
languages are probably on about equal footing for job/hardware
control and possibly IFS access.
