Unless the delay is somewhere in the generic mac80211 stack. The older Atheros hardware is unique, because it has not just two hardware drivers but also two 802.11 stacks. It would be nice if somebody could do a similar test with two different 802.11 stacks and drivers. Comparing the performance between libertas and libertas_tf might provide an interesting data point. -- Regards Joerg
