I am using Apache Commons FTPClient to upload large files, but the transfer speed is only a fraction of transfer speed using WinSCP via FTP. How can I speed up my transfer?<
It would be better if you use
ftp.setbuffersize(0);
if you use 0 as your buffersize , it will take as infinite buffer size.
obviously ur transaction will get speeded up... I personally experienced it..
all the best... :)
