If you're trying to solve a problem, it's much easier if you can look at smaller parts of the problem in isolation. Using ttcp or NetPerf is an effective way of removing the disk subsystem from the chain. If you're getting 1 MByte/s with ttcp/NetPerf, combined with reasonable CPU usage, *then* it may be time to look at why the CPU usage is not reasonable with FTP.
