Right. It's easier to say this than to do it, of course, and sometimes there simply isn't a (known) better way. In that case, judicious use of these other techniques can usually improve performance with little cost and significant results. The best results are obtained with a combination of all of these techniques - good algorithms, compiler optimizations, various hints to the compiler (like pragma Inline), and suppressing selected checks (using pragma Suppress) where it's known that problems can't occur.
