Latency is always that with ePMP on dfs... as far as I can tell it's pretty much the same whether you use flexible or fixed ratio... and ePTP doesn't support dfs last I checked.

    OK so back to ePMP PTP. I had to put up a 500' link between two
    grain legs. Used integrated radios on 2.4.3. I tried ePTP, but
    they wouldn't link up. Thinking maybe too short? I don't know, so
    I just switched them to TDD PTP w/ flexible framing instead.
    Latency is like 15ms. I hate it. I have a couple other links still
    on 2.3.3 also doing flexible framing and latency is very
    consistently 7ms. Only thing I can think is that this new short
    link is on 5.4GHz and it's actually forcing fixed framing (even
    though it says flexible) because of DFS? Either that or something
    is very different between 2.3.3 and 2.4.3.

    Anyway.. we were thinking about switching out a bunch of 5GHz
    Rocket links (because they cannot handle noise at all) with ePMP
    GPS. We get very good latency with the Rockets, typically under
    3ms when the front ends aren't swamped, but I will NOT do 15-20ms
    with ePMP, that's just stupid. The whole idea was sync, and since
    ePTP doesn't sync.. not sure what to do. Maybe 2.5ms framing and
    50/50 TDD will get me 7ms, and w/ sync?
