Any noticeable performance penalty? Any benchmarks?
- epmaybe 9y agoYes, what kind of real world performance will users notice?
- gbrown_ 9y agoThis is the real question, too many people seem to be blindly throwing around "Regression of X%". Phoronix have put out some benchmarks for Linux [1][2]. As one may expect I/O seems to be hit noticeably given it's handled by the kernel.

- jorvi 9y agoThe question becomes: does Apple need to compensate customers? If Ford sold a car with a certain amount of torque advertised, and then an ECU patch (due to emission problems) slashed that torque by 30%, you bet they’d have to compensate either monetarily or with a buyback. MacBooks go for as much as secondhand cars too.

- pier25 9y agoI imagine Apple, and all PC manufacturers.
