Fast and tiny FTP server for Windows
At some point I found myself in a need of ftp server for windows to test things. Googling gave me ftpdmin, which is free and really tiny, also opensource. However it struck me as being real slow - downloads on 1GB network were mere 5MB/sec with one core fully busy. Looking inside it was thread per connection and 4kb blocking network calls. Of course I had to roll my own FTP server after that!
Uses IOCP via asio, io_service per core, uses async (with some ugly hacks in uploads). Also uses TransmitFile for downloads which is virtually free. Borrows a bit of source from ftpdmin.
HAS BUGS (one thing I`m sure of)
HAS ZERO security hardening.
Usage: TinyWinFTP.exe Dir Port
