   - High performance: The single-core QPS reaches 18k with an average delay of fewer than 0.2 milliseconds.
   - [Fault Injection](docs/en/latest/plugins/fault-injection.md)
   - [REST Admin API](docs/en/latest/admin-api.md): Using the REST Admin API to control Apache APISIX, which only allows 127.0.0.1 access by default, you can modify the `allow_admin` field in `conf/config.yaml` to specify a list of IPs that are allowed to call the Admin API. Also, note that the Admin API uses key auth to verify the identity of the caller. **The `admin_key` field in `conf/config.yaml` needs to be modified before deployment to ensure security**.
