Ping. This set has been on the list two months now. We use l2fwd to measure raw packet IO performance with and without scheduler. As long as the scheduler mode of the application is un-optimized, scheduler mode results are worse than those should be. A perfect HW scheduler does not help, if the test itself loses cycles.
