### Changing the number of workers
When you run bitwarden_rs, it spawns `2 * <number of cpu cores>` workers to handle requests. On some systems this might lead to low number of workers and hence slow performance, so the default in the docker image is changed to spawn 10 threads. You can override this setting to increase or decrease the number of workers by setting the `ROCKET_WORKERS` variable.
In the example bellow, we're starting with 20 workers:
```sh
docker run -d --name bitwarden \
-e ROCKET_WORKERS=20 \
-v /bw-data/:/data/ \
-p 80:80 \
mprasil/bitwarden:latest
```
### Other configuration ### Other configuration
Though this is unlikely to be required in small deployment, you can fine-tune some other settings like number of workers using environment variables that are processed by [Rocket](https://rocket.rs), please see details in [documentation](https://rocket.rs/guide/configuration/#environment-variables).
