Performance: COBOL trounces C / C++?
<snip>
We *always* see a huge discrepancy in the performance of these
programs, C always being many times slower.
Although I am at a loss as to why.
If I take the same code (Cobol / C / C++) and use it on other
platforms
i.e. Unix or Windows the performance of the code is very similar.
This
leads me to the conclusion that the complexity of the code is nearly
the same.
I must then turn to the systems themselves : Mainly the compilers
and
system related code.
I truly find it difficult to believe that the IBM C compiler is so
horribly ineffective, or that the COBOL compiler is just that much
better at generating efficient code. **There must be a way to bring
our C code's efficiency near that of similar COBOL code.

IBM (lately meaning the last 10 years or so) some of their compilers &
run Time) have been spectacullary bad. (LE as an example took 10 or so
releases before they are close. I would not expect a newer language to
be much better.
COBOL has had quite a few different names & releases.
The PC weenies (IMO) have taken over the and run it like MS. They don't
seem to care about the poor end users anymore.
So anything that is bad you will have to complain about quite loudly at
SHARE . Don't count on it though but it wouldn't hurt.
