I'd sure advocate faster processors, but I seem to disagree with your
logic here. I don't think a faster processor is the only solution to a
poor compiler. I'd prefer that the software guys tie the C++ string copy
to the MI instruction used by RPG.

I think there is a difference between "consumed" and "needed" and it
might not be that it is all needed here. Maybe standard C++ and Java
libraries should rely on MI instructions. Otherwise it seems like you
are saying, "See, when I used it like a PC server it isn't as good as a
PC server."
