- Removes the accept() loop, as that doesn't measurably improve performance in practice. This also gives each connection the possibility to perform initial I/O before more concurrency is generated by accepting the next connection. - Uses SOCK_NONBLOCK in conjunction with socket() and accept4() to save one additional syscall per connection. |

EventCore
This is a high-performance native event loop abstraction for D, focused on asynchronous I/O and GUI message integration. The API is callback (delegate) based. For a higher level fiber based abstraction, take a look at vibe.d.
