evloop

A thin ATS2 wrapper over system async APIs (epoll,kevent,poll), modeled closely off of the libh2o event loop.

Works, but is in early stages. This was intended to be a component of a larger embedded server project. Performance seems promising:

(test02 HTTP/1.1 "Hello World," 4-cores @ 2.30GHz)

[mall0c@core-99 ~]$ wrk -t 3 -c 1000 http://localhost:8888/

Backends

Asyncnet currently supports the following backends. To use, compile with the given flag:

• epoll (-DATS ASYNCNET_EPOLL)
• kqueue (-DATS ASYNCNET_KQUEUE)
• poll (-DATS ASYNCNET_POLL)

This is known to work on Linux and OpenBSD, but has not been rigorously tested.
