Software optimization

I can´t cheat changing the file format hehe. Actually im pretty satisfied with my parser speed now, thank you all, your tips were very usefull!

What do you mean by cheating?

It is always nice to have an easily readable file.

I think what the OP means is that the original file format is fixed, and can't (easily) be changed.

matsp is right.

Ok, im a tireless optimizer, i have improved t3 performance mark with the following parsing:

Code:

---

        for (string::size_type i = 0;;)
        {
                while (line[++i] == '-' && i < end); //find first '-' character

                if (i >= end) { break; }

                begin = i;
                while (line[++i] != '-' && i < end); //find first not of '-' character

                dictionary[line.substr(begin, i - begin)]++;
        }

---

I was able to squeeze out 1,266 seconds from this function, over the 1.5s of before...
