Interesting. I am just running top through ssh from my VPS, and when I either manually spam transactions or do a flood_network command I see a dramatic increase in the CPU usage of witness_node. Up to 100% (its a dual core VPS, and I think top just references the core its running on) Would there be a better way to test it locally, or would it be better to find a way to sync better between multiple users? IRC, or Mumble?
