# Network Performance Analysis

### Overview

This sample shows how to use **PerformanceTiming()** to obtain detailed timing information about each phase in an HTTP data request process in a table.

```

### How to Implement

1. Create an HTTP request and set the **headersReceive** callback.
2. Set request parameters, including **method**, **header**, and more.
3. Initiate a request.
4. Parse the response, in which **performanceTiming** provides the time used in each phase of the request process.

### Required Permissions

- **ohos.permission.INTERNET**: allows an app to access Internet.

- **ohos.permission.GET_NETWORK_INFO**: allows an app to obtain network information.

- **ohos.permission.SET_NETWORK_INFO**: allows an app to set network information.
