[question] listen_queue

[Misakiwa]

I'm running test python app that's basicly hello world and using nginx and uwsgi, i'm trying to load test it with such command: wrk -t 8 -c 1000 -d 60s http://localhost
However when i see in my stats its always show "listen_queue":0.

Can you help, why it's not changing at all?
Thats my ini:

[uwsgi]
module = wsgi:application
chdir = /var/www/python_app
plugins = python3
#max-requests = 5000
processes = 1
threads = 1
master = true
#http = 0.0.0.0:8080
die-on-term = true

socket = wsgi.sock
chmod-socket = 660
vacuum = true
uid = www-data
gui = www-data
listen = 10

stats = 127.0.0.1:9191
stats-http = true

enable-threads = true
thunder-lock = true

And nginx:

server {
	listen 80 default_server;
	listen [::]:80 default_server;

        location / {
                #try_files $uri $uri/ =404;
                include uwsgi_params;
                uwsgi_pass unix:/var/www/python_app/wsgi.sock;
                try_files $uri $uri/ /wsgi.py?$query_string;
        }
}
