Please send me detailed instructions, as well as information about how much= traffic I'm going to have to pay for. FWIW, the RTT of the (unloaded) link varies tremendously. Right now (aroun= d 21:20), I'm seeing 89ms to 823ms, with an average of 192ms and a standard= deviation of 146ms. It's better at night, mid-morning it's pretty much un= usable. -- Juliusz _______________________________________________ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat
