Do you realize that you push anything between zero and 2 Mbytes through the MD5 routine, no wonder that it, sometimes i guess, takes time to generate a key.
Considering that, it's actually remarkably speedy. If I'm just generating one key at a time, it is basically instantaneous. 50,000 keys took about 5 minutes (not bad, all things considered). In the application I have (see Update, please), I'm not generating more than 50 keys in a given 1s interval, but they absolutely must not duplicate.
Still, I will be exploring some of the tips in this thread regarding faster ways to accomplish the same thing; hopefully I will remember to update my snippet when I get around to testing them!
