Do I need more workers to use more CPU cores or threads simultaneously?

The user is asking if they need more workers to utilize more CPU cores or threads simultaneously. The solution is to change the `_APP_WORKER_PER_CORE` in the `.env` file. It is recommended to either use a ratio or add more cores. Self-hosted Appwrite uses 6 workers per host core by default. It is not clear if a single worker can use multiple CPU cores.
