Great. Keep in mind there's multiple hardware this drivers sits on. If your clearfog hardware usues the software buffer manager then you can test. We haven't done any changes to the 'hardware buffer manager' portion of the code though. Test wise, you should see similar numbers for 64b-256b packets since the driver internally recycled buffers for packets of that size. The tests we did with 256b-512b packets showed significant increases. Thanks! /Ilias
