All the recent microcode patches to fix CPU security flaws have caused performance degradation, so it's fair to mention that people have been upset about this in the past (anecdotally, I know first-hand that people have disabled the patches because it's started to break software that has significant timeouts -- and they were obviously not happy that this was necessary). It's also (somewhat) fair to assume that this patch would also affect performance until proven otherwise, and Intel changing their license to disallow sharing comparative performance tests doesn't give me much faith that I'm wrong in that assumption.
