Time between frame submission to firmware and tx-completion on one of my ath10k machines: Legacy 54mbps: ~18ms Legacy 6mbps: ~37ms 11n MCS 3 (nss=0): ~13ms 11n MCS 8 (nss=1): ~6-8ms 11ac NSS=1 MCS=2: ~4-6ms 11ac NSS=2 MCS=0: ~5-8ms Keep in mind this is a clean room environment so retransmissions are kept at minimum. Obviously with a noisy environment you'll get retries at different rates and higher latency.
