16 ngx-local-relay for each published stream, is it right ?

[ffallah]

I have a server with 16 cores and I have these options in my nginx config :

multi_accept on;
worker_processes auto;
rtmp_auto_push on;

For every stream which gets published, it seems all nginx workers start consuming it through ngx-local-relay, I am not sure if it is the intended behaviour or not :

Any ideas ?
