| Method | Linux | macOS | Windows | BSD | Solaris, HP-UX, IRIX, Tru64 | Notes |
|--------|:-----:|:-----:|:-------:|:---:|:---------------------------:|:------|
| select | X     | X     | X       | X   | X                           | Least efficient, but widest support  |
| poll   | X     | X     |         | X   | X                           | Low efficiency, but wide support     |
| kqueue |       | X, Go |         | X   | Go                          | Efficient |
| epoll  | Go    |       |         |     |                             | Efficient |
| /dev/poll |    |       |         |     | X                           | Efficient |
| eventport |    |       |         |     | Solaris 10+, Go             | Known problems, use /dev/poll instead |
| IOCP   |       |       | X, Go   |     |                             | Recommended for Windows |

Goland runtime uses `epoll`/`kqueue`/IOCP so no need for `libevent` or similar.
