unix command required.

I need to get a few details from the command line. I need to get the kilobytes per second that my server is transfering to another or has available and I need to test the connection to make sure that its a sound connection. I also need to keep track of the response time.

I have been playing around with iostat,netstat. Are there any better alternatives and command line switches that will give me better information. Are there any guides that tels what a sound connection is and fields to look out for?

Any help would be great.

I see you are asking about transferring files...
You can ftp from 1 server to another server...
Remember to type
hash
bin
in the ftp prompt before you start the ftp...

You can see the speed of the ftp after the job is done.

You might also wanna do an iostat -xntc 3 on the target / destination server to see if the disks are driven to the max... E.g. 100% busy

Using netstat is not very useful as the output is in pkts but you can use netstat to detect collision in case the ftp is slow.
