John Plevyak created TS-3044: -------------------------------- 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 -- This message was sent by Atlassian JIRA (v6.2#6252)
