The only new option here is `--workers` telling Uvicorn to start 4 worker processes.

You can also see that it shows the **PID** of each process, `27365` for the parent process (this is the **process manager**) and one for each worker process: `27368`, `27369`, `27370`, and `27367`.

Buradaki tek yeni seçenek `--workers`; bu seçenek Uvicorn'a 4 adet worker process başlatmasını söyler.

Ayrıca her process'in PID'inin gösterildiğini de görebilirsiniz: parent process için `27365` (bu process manager), her worker process için de bir PID: `27368`, `27369`, `27370` ve `27367`.
