The proper way to do asynchronous io on Windows is quite different from
the proper way to do it on posix systems (more or less everything other
than Windows). If you plan on using a Windows server, pay no attention
to benchmarks run on posix servers. More on this below.

Stackless used 'micro threads' managed by the interpreter without
involving the OS. These are called 'green threads' because they save
resources. They are available as 'greenlets' on PyPI and used by, among
others, gevent. See

Python 3.4 comes with something similar -- tasks -- in the new asyncio
library. On feature of asyncio is that it transparently implementation
so the same asyncio code works well on Windows as well as posix. I don't
know if this is true of other alternatives.
Python has an ftplib module. I suspect it could still be improved to
work better with asyncio.
