Firstly no one will use one single computer. They will use mutliple computer simultaneously like on cloud or something. They exploit the vulnerabilies in system rather than going on good old brute forcing. Then they work on guess work, personal information etc as guess work. They first get your password files from the servers if they really want to crack your password. Attacking server directly with password will not work at all, Gmail, yahoo mail or most companies are fvcking fortresses.
It is not quite that simple, but if there is a problem it will be explioted. Crackers are after zero day exploit.
