Hi, yeah 
100GB/day is it per each node?
Because 100GB/day is usual but shared between nodes on same public IP (as you can see in thread above) … - that gives around 1.3-1.5 MB/s per public IP.
But your snapshot your picture from different thread
suggests that you get ~60Mb/s->6.25MB/s - you have 4 nodes so ~1.5MB/node
given that you have 2 separate internet intakes gives you 2x more on top of what our nodes achieve.
That is what really stumps me here
