Re: [Dev-C++] speed test

[Per W. <pw...@ia...>]

What should be noted is that your test code doesn't test the speed of the
Dev-Cpp++-generated program - which in fact is the MingGW- or
Cygwin-genrated - but instead measures the time to process a couple of
million bytes of output to standard out.

Do you redicrect the output, or is it scrolling in a text window. What
size is the text window etc.

This kind of programs also notoriosly generates a large percent of system
(kernel) time, giving the OS scheduler some extra concerns about how to
schedule between this and other programs.
