How does this compare to with normal poll on this system? In other words, what advantage is there to using epoll instead of poll when busy looping? epoll and busy_poll seem to be opposites. epoll inherently has higher latency than normal poll, but provides stable performance with many more FDs. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
