What is the best way to transfer big files to the RPi?
Now I've test this options:

• transmission (torrent) - up to 5 Mb/s
• Samba from windows PC - 6Mb/s at start, after few seconds avg. spd 1-2Mb/s
• sftp (WinSCP) - less than 1Mb/s
• wget (using HFS as web-server) - up to 4Mb/s, avg - 1.5Mb/s
  

RPi uses wifi connection, at this time avg. spd is around 40 mb/s (up and dl), max is 60 dl and 50 up (iperf).
