Best file transfer protocol : Which to use among SMB, Socket (TCP/UDP) and FTP?

I had gone through the requirement of file transfer using peer to peer in a same network. I tried the case of server and client too because I had not any issue to run server script (in case of Socket Connection). Main purpose was to attain maximum transfer speed of data. So I tried with three most popular protocols for file transfers which are –

• SMB – Server Message Protocols known also as sambha file sharing

• Socket- Work on the base of client server concept

• FTP- File transfer protocol

Comparison for performance –

Phone	Protocol	Data	Distance	Time	Max Speed
XOLO	Socket	1.3 GB	5 Meter	16 Min	1.3 MB/S
XOLO	SMB	0.7 GB	5 Meter	25 Min	0.5 MB/S
XOLO	FTP	1.3 GB	5 Meter	14 Min	1.6 MB/S

Notable Point about file transfer protocols –

• Socket – Server scripting required for file transfer. This connection cannot be named as peer to peer

• SMB – No scripting required for file transfer. It can read any file structure of peer computer

• FTP – FileZilla can do the trick for file transfer. No Server script required

Term and Condition – These all testing has been done between an android and a low configuration desktop (Windows 7). Both were connected to one dedicated wifi local network
