how to achieve high speed rate in file transfer


Hi,
Can anybody please help me regarding any tool that is suitable for high speed data transfer.
I am doing some FTP file transfer on 100 mbs links on both sides. The FTP transfer is just occuring at the rate of 10 mbs . I have done the necessary tuning for the TCP window size.There is no other traffic , so it is expected that I should receive transfer rate of more than
80mbs per second. So is there is any tool that is suitable for high speed data transfer.

don't forget that a 100mbps link can only transfer at a theoretical maximum of about 12 megabytes per second...

On what basis you are saying that. Please explain me or any links
that discusses whatever you have written.

because one byte = 8 bits. one Mbyte = 8Mbits, 12Mbytes ~ 100Mbits.

And 12Mbytes/s includes the header and acknowledge. Not much but if you look at the speed in your ftp client (data only) then probably you won't get more than ~ 11Mbytes.

I would be surprised to see that ssh is faster than ftp?? Might more be the opposite actually.

SSH is going to be slower than non encrypted protocols. The reason for this is because of the added overhead caused by encrypting/decrypting the packets on both ends that is unnecessary otherwise when using FTP.

I would say upgrade to gigabit if you want faster speeds. However at that point you will most likely find your systems I/O will create a new bottleneck.
