There are several at project's homepage [1] and in archive [2]: evserver_epoll.c - epoll-based web server (pure epoll) evserver_kevent.c - kevent-based web server (socket notifications) evserver_poll.c - web server which uses kevent-based poll (poll/select notifications) evtest.c - can wait for any type of events. It was used to test timer notifications. naio_recv.c/naio_send.c - network AIO sending and receiving benchmarks (sync/async) aio_sendfile.c - aio sendfile benchmark (sendfile/aio_sendfile). Kernel implementation is not 100% ready, pages are only asynchronously propagated into VFS cache, but are not sent yet. There are also links to benchmark results, comparison with FreeBSD kqueue, some conclusions on kevent homepage [1]. Network AIO [3] homepage also contains additional NAIO benchmarks with some graphs. 1. kevent project home page. http://tservice.net.ru/~s0mbre/old/?section=projects&item=kevent 2. kevent archive http://tservice.net.ru/~s0mbre/archive/kevent/ 3. Network AIO http://tservice.net.ru/~s0mbre/old/?section=projects&item=naio Current development kevent patchset (against 2.6.15-rc7, but could be applied against later trees too) attached gzipped, sory if you get this twice.
