As somebody who is now debating how to measure latencies in a giga-bit ethernet environment with several components doing L3 switching in much less than 10 micro-seconds ... (hardware) I agree that some method is need to achieve higher resolutions. (Sigh... I will likely need to buy something big and expensive) {this is for a system to make use of L.
