Currently it's ran on granet with the CLI: `/opt/swhgraph_venv/bin/python3 /opt/swhgraph_venv/bin/swh graph rpc-serve -g /dev/shm/swh-graph/default/graph`
This means it uses a single process, which is currently the bottleneck when processing a dozen queries in parallel.
This CLI should work: `gunicorn3 -p /run/gunicorn/swh-graph/pidfile swh.graph.server.app:make_app_from_configfile()`
