Hi,

I am not sure how the load balancer affect the data throughput.

For example: I have two nginx server with 1 Gps network connection.
When I configure the first server as nginx load balancer and as upstream server and the second server only as upstream server.

Is the second upstream server sending its data directly to the client or is the data routed through the load balancer (first server). When all data is routed through the first server I have only a maximum bandwith of 1 Gbps. If the second server sends his data directly to the client I have a maximum bandwith of 2 Gbps. And if the second server sends its data directly to the server, does the response data contain the ip of the second upstream server?

So which one is correct?

Best Regards
Wolfgang
