Binary wheels are now provided for Windows, MacOS, and Linux (amd64 and arm64). tornado.gen coroutine now has better support for the Python 3.7+ contextvars Tornado 2.1.1 Oct 4, 2011 Bug fixes Fixed handling of closed connections with the epoll (i.e. Linux) IOLoop. Previously, closed connections could be shut down too early, which most often manifested

Tornado should run on any Unix-like platform, although for the best performance and scalability only Linux (with epoll) and BSD (with kqueue) are recommended for production deployment (even though Mac OS X sleep]. IOLoop objects class tornado.ioloop.IOLoop A level-triggered I/O loop. We use epoll (Linux) or kqueue (BSD and Mac OS X) if they are available, or else we fall back on select().
