Second, it queues the events onto a handler in the same thread rather than doing the io_submit itself. Third, if the handler which calls io_getevents on an EThread, there is already another call to epoll() which is blocking the same thread. Having two calls on the same thread blocking the thread is not a good idea: they will conflict with one blocking while the other has ready data (i.e. from the net or from the disk). If io_submit is thread safe while there is an currently waiting io_getevents on another thread, then linux aio might be viable for traffic server. If io_getevents played well with epoll() then linux aio might be viable. Really, to get this to work Linux would need to have an integrated async completion API. use linux native aio Key: TS-1760 URL: https://issues.apache.org/jira/browse/TS-1760 Project: Traffic Server Issue Type: Improvement Components: Core Reporter: weijin Assignee: weijin Fix For: 3.3.2 Attachments: native_aio.patch add a feature that use linux native aio -- This message is automatically generated by JIRA.

Effective only on the linux system. +# 2, I think that is because that glibc aio is a user thread implement like our own AIO, and we need some performance improvement in this patch, in our testing, the cpu usage may get 5% less than origin threading AIO, and the disk hit response time may get into 5-10ms, that is much better than before.

Unless it's truly Linux specific, I'd prefer a different name on that config option. For example, if it's a glibc only thing, it'd be much better to call it --use-glibc-aio. If it's Posix AIO under the hood, then --use-posix-aio (you get the idea ;).
