Rocket -max simplex ( one direction) throughput BW 20 Mhz -( udp,1470), UL/DL= 75.3/78.4 mbps -(udp,64 bytes) UL/DL= 11.4/12.3 mbps Max simplex throughput (udp, 1470) BW 40 MHz ( udp,1470), UL/DL= 95.5/95.5 mbps - limited by 100 BaseT -(udp,64 bytes) UL/DL= 7.6./8.6 mbps RB411, MPLS; 5GHz-only-N; Nstreme OFF Polling disable,CSMA enable showed aprox the same results. Nstreme ON in 802.11n mode gives worse results at small packet traffic.

Problem is connected with MAC802.11a/b/g and also 8022.11n implemetation. Using more powerfull CPU does not resolve it. We tested TDMA freebsd Sam Lefler MAC 802.11a implementation .at the simular platform ( Alix, CM9) . It also has poor throughput at small packet size ( but much better then standard 802,11a) and it is may be improved by using more powerfull h/w.
