### Install `tuned.conf` performance profile

#### Step 1 - download `tuned.conf` from the referenced link
```
wget https://raw.githubusercontent.com/minio/minio/master/docs/tuning/tuned.conf
```

#### Step 2 - install tuned.conf as supported performance profile on all nodes
```
sudo mkdir -p /usr/lib/tuned/minio/
sudo mv tuned.conf /usr/lib/tuned/minio
```

#### Step 3 - to enable minio performance profile on all the nodes
```

        val startReleaseCycle = model.findBuildTypeByName("Start Release Cycle")

        val steps = startReleaseCycle.steps.items
        assertEquals(1, steps.size)

        val step = gradleStep(steps, 0)
        step.assertTasks("clean promoteStartReleaseCycle")

You could also use it to generate code automatically, for clients that communicate with your API. For example, frontend, mobile or IoT applications.

## Recap, step by step

### Step 1: import `FastAPI`

{* ../../docs_src/first_steps/tutorial001.py hl[1] *}

`FastAPI` is a Python class that provides all the functionality for your API.

/// note | "Technical Details"

## Making changes

### Step 1. Make changes in charts and values.yaml in `manifests` directory

Be sure to provide sufficient documentation and example usage in values.yaml.

- If the chart has a `values.schema.json`, that should be updated as well.

### Step 2. Update the istioctl/Operator values

If you are modifying the `gateway` chart, you can stop here.
