How do you test preformance of your program/functions?
I just use GetTickCount().. Are there better ways to do that?
When to know your program/function works good?
I've just done function for searching variables in text (using boost::spirit), and if I call it with about 400 variables 400 times (about 300 chars long text) it takes about 9500 miliseconds (which sounds a lot)..
