About

Python FTP server library provides a high-level portable interface to easily write very efficient, scalable and asynchronous FTP servers with Python. It is the most complete RFC-959 FTP server implementation available for Python programming language.

Features

Extremely lightweight, fast and scalable (see why and benchmarks).
Uses sendfile(2) (see pysendfile) system call for uploads (Linux only).
Uses epoll() / kqueue() / select() to handle concurrency asynchronously.
...But can optionally skip to a multiple thread / process model (as in: you'll be free to block or use slow filesystems).
Portable: entirely written in pure Python.
Supports FTPS (RFC-4217), IPv6 (RFC-2428), Unicode file names (RFC-2640), MLSD/MLST commands (RFC-3659).
Support for virtual users and virtual filesystem.
Flexible system of "authorizers" able to manage both "virtual" and "real" users on on both UNIX and Windows.

Performances

Despite being written in an interpreted language, pyftpdlib has transfer rates comparable or superior to common UNIX FTP servers written in C. It usually tends to scale better (see benchmarks) because whereas vsftpd and proftpd use multiple processes to achieve concurrency, pyftpdlib only uses one (see the C10K problem).
