UDWee makes UDP go weeeeeeeeee as in really fast. It uses the following approaches on each platform:
- macOS / BSD: SO_REUSEPORT and thread-per-core I/O.
- Linux: SO_REUSEPORT and thread-per-core with
recvmmsgandsendmmsg(and io_uring possibly in the future) - Windows: TBD
It's designed for use with ZeroTier but can be used by other projects as well. The InetAddress class from the ZeroTier common utilities crate is used instead of the usual SocketAddr as it can easily be cast to/from the low-level OS sockaddr structures, but it implements into/from traits for SocketAddr and friends.
