When i redid it properly kevent showed no significant advantage over epoll. Note that i did those measurements _before_ the recent round of epoll speedups. So unless someone does believable benchmarks i consider kevent an over-hyped, mis-benchmarked complication to do something that epoll is perfectly capable of doing.
