# Configuring the requests per second (RPS) target

This setting specifies a target for requests-per-second per replica of an application.

* **Global key:** `requests-per-second-target-default`
* **Per-revision annotation key:** `autoscaling.knative.dev/target` (your revision must also be configured to use the `rps` [metric annotation](autoscaling-metrics.md))
* **Possible values:** An integer.
* **Default:** `"200"`

**Example:**

=== "Per Revision"
    ```yaml
    apiVersion: serving.knative.dev/v1
    kind: Service

      name: helloworld-go
      namespace: default
    spec:
      template:
        metadata:
          annotations:
            autoscaling.knative.dev/target: "150"
            autoscaling.knative.dev/metric: "rps"
        spec:
          containers:
            - image: gcr.io/knative-samples/helloworld-go
    ```

=== "Global (ConfigMap)"
