I have made a torrent client/file server with raspberry pi 2, using a 16 GB SD card class 10 for raspbian and a 16 GB USB to store files that i transferred with samba. Pi is connected with LAN cable with the speed of 680 KB/sec.
During the transfer, the smbd daemon is using 1-2% of CPU and has up to 500 MB of RAM free, any ideas?
