Are the events put directly in the ring buffer, when using that mode? Or are they held in some other place, then copied there at kevent_wait time, like this article seems to imply?
If it is the latter, what is the difference (in performance or otherwise) between copying them at kevent_get_events time or copying them at kevent_wait time?
It seems to be to be just the same, with the ring buffer just having a starting point that "moves around" instead of copying at the beginning all the time. If anything, I wouldn't be surprised if copying at the beginning all the time would be better for cache footprint (and thus slightly faster)...
