Trying to increase performance of mask attack with a two character prefix

[Plexus]

The next time you can complete 10^16 on salted md5 fast enough to win a round, let me know. You are looking for  2.77TH/s if the round wait time is roughly an HOUR long. That's 2777000000000 attempts per second to complete the keyspace in an HOUR. Not even in the same league as your achieved max of 650Mh/s(650000000). That's 75 1080Tis or something roughly in that general area of power. And, on top of this being absolutely infeasible, you literally just admitted that you were trying to hack a gambling site. This is not a hacking forum. Please take stuff like this somewhere else.

I don't see where I admitted that I was attempting to "hack" anything, all I said it was possible. You assume that a theoretical winning percentage is hashed using a salt when this is not always the case. Also, who says you need to hash all 10^16 combinations when something like 10^12 is perfectly fine. 10^12 hashes would allow for 1 in 10,000 potential games to be known which is pretty decent if there are a couple of thousand games a day. Also this still has nothing to do with my question.
