ntttcp Overview

There are two switches on ntttcp that boost performance: -aand -rb.

ntttcp can be run without an optimal value for the -aswitch and without the -rbswitch for the QLE3044.

When running ntttcp with the QLE3142, and in particular with fewer threads on Windows Server, performance is limited by the receive window and by the outstanding I/O (-a) value, regardless of hardware limitations.
