Nginx or LVS for load balancing Node.js?

Our project should balance the load of TCP packets to node.js.

Offer: (Nginx or LVS) + Keepalived + Node Cluster

enter image description here

Questions:

  • High concurrent client connections to the TCP server must be durable. Which one is more suitable, Nginx or LVS?
  • We need to set different priority levels for Node master on the main server (the priority of the local server will be higher than the remote servers). Who can do this, Nginx or LVS?
  • Whose processor load is lower and bandwidth is higher, Nginx or LVS?
  • Any recommended documents for comparing performance / performance features between Nginx and LVS?

Finally, we wonder if our proposal is reasonable. Are there any other best deals or components to choose from?
