John specifically spoke to the issue of I/O performance in COBOL vs RPG.
RPG (at least, used to) do a field by field translation on record I/O.
COBOL and PL/I did not.
That made (as I can attest to from those days) COBOL faster for I/O
intensive applications.

It's hard to imagine how that could be true. I can imagine a particular
RPG compiler generating worse code than a particular COBOL compiler, but
I can't imagine how all RPG compilers would generate worse code than
all COBOL compilers.
