Thanks, do you think it would be fair to assume that using a smaller PDU would transport the same amount of data more reliably at the expense of lower throughput? My logic would be that a longer PDU is more likely to encounter a bit error, so more likely to encounter enough successive failures to trigger CONNECTION_TIMEOUT. Smaller PDU requires more sends to transport same amount of data, but each success resets timeout/retry logic. Or, is there lower level logic that would contradict this assumption?
