Ok, this is more similar to what I'd expect (3.6 * 6 / 4 = 5.4, I'm not sure if you have the memset optimization in the send-batching test). Hex is obviously more debuggable compared to Base64 (unless you starred in the Matrix movies), so I'm a bit undecided about this one. Anyone can break the tie? Paolo
