Bursting will get you to ~28 and FF's are likely the reset (no dynamic turbo on freebsd). It would be nice to have control in linux to explicitly turn on/off bursting but the usual way people do it is to negotiate wmm and force the txop limit. BTW whenever you see a performance difference the first thing to look at is packets/sec. I've not found any linux tools that give me this a la athstats/wlanstats on freebsd. -Sam -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
