             Summary: linux native AIO should use eventfd if available to 
signal thread
                 Key: TS-3044
                 URL: https://issues.apache.org/jira/browse/TS-3044
             Project: Traffic Server
          Issue Type: Improvement
          Components: Cache
            Reporter: John Plevyak


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
