Yep, like I wrote you yesterday ( and you did not answer ) is that I was trying to add supprt for AIO into the test HTTP server I use to do benchmark tests ( http://www.xmailserver.org/linux-patches/ephttpd-0.1.tar.gz ) but since there's no support for AIO POLL, it is impossible ( at least to my knowledge ) to compare sys_epoll and AIO on a "real HTTP load" networking test.
