Well, given the lack of 40Mhz channel support, the best we can do in theory is 72.2 Mbit/s (20 MHz channel with SGI, see mcsindex.com). But since we don't support Tx aggregation yet either, protocol overhead eats up a huge chunk of that. The peak iwm(4) Tx rate I have measured with tcpbench(1) is about 20 Mbps. Receive can be faster because 11n APs usually send aggregated frames and we do support receiving such frames.
