That's because SSL is a shitty protocol, it has nothing to do with CPU. Turns out that you can only have one SSL applied to one IP because browsers* can't tell the webserver hosting 1,000 sites which particular site you're requesting, because of, you guessed it, encryption. Essentially, you're paying for a dedicated IP not CPU. *theres a fix for this supported by several browsers, but it will never be backported to legacy browsers and the millions who won't upgrade for many years so its unsafe to assume you can use this method, thus one IP per SSL for the foreseeable future.
