Honestly, I think it's your CPU. Run top while doing your throughput test, and I think you'll see 100% sirq (pegged CPU core). Also make sure you split the CPU's up so you're not looking at the 'total' cpu count. - Pushpal _______________________________________________ ath10k mailing list ath10k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath10k
