> Project: Traffic Server
> Issue Type: Improvement
> Components: Cache

> Attachments: native-aio-eventfd.patch
>
>
> linux native AIO has the ability to signal the event thread to get off the
> poll and service the disk via the io_set_eventfd() call. linux native AIO
> scales better than the thread-based IO, but the current implementation can
> introduce delays on lightly loaded systems because of the thread is waiting
> on epoll(). This can be remedied by using io_set_eventfd
