Minecraft’s networking stack specifically uses Epoll on Linux, their native transport, which increases speed. No such consideration is given to macOS, where KQueue is able to be used. It is not. Instead it falls back to the slower NIO.
I believe this to be a bug since special consideration was given to Linux to use Epoll, which has a (presumably) smaller usage-base than macOS.
