Why the downvote? Is it such heresy to say that many users care more about performance than security? I’m not suggesting that security is unimportant, just that it’s not very compelling if it’s at the expense of performance. For example see all the recent Intel processor exploit patches. Personally I would take an obscure attack vector on my private desktop computer over a ~5% performance loss.
