Not getting a high performance compared to `gunicorn`

[Zeyad Moustafa]

So I started a Django project and compared gunicorn and granian but noticed no difference at all. This confuses me as I thought using a Rust-based server would be way more efficient than a Python-based one. Here is what I got using hey

Using gunicorn :

The command in gunicorn is: gunicorn -w 16 --threads 16 project.wsgi:application

and the command in granian is : granian --interface wsgi --workers 16 --threads 16 project.wsgi:application

The page loaded is the default page for Django applications a simple HTML page. So is there anything I have done wrong or this is a normal thing??
