This is clear :)

In example if you have 4 cores you create 4 qgis-server socks file and 
put every soscks in a nginx upstream:

upstream qgis_mapserv_backend {
         server unix:/run/qgis-server1.sock;
         server unix:/run/qgis-server2.sock;
         server unix:/run/qgis-server3.sock;
         server unix:/run/qgis-server4.sock;
}

In this way?

Grazie
