I have a few hops that are exactly like that, root. Something like 3 in a row with massive packetloss, yet I don't lag. They may or may not be the problem, but it's certain that there shouldn't be any packetloss coming before those. GhostyFish, can you post a trace to DSB with 50 or more cycles, and also to another zone with 50 or more cycles? It will help better determine the problem.
