1# SmartPerf User Guide 2 3## Introduction 4 5SmartPerf is a reliable, easy-to-use performance and power consumption test tool. In this tool, you can measure the performance and power consumption of your application with quantitative indicators, such as FPS, CPU, GPU, RAM, and Temp. 6 7Targeted at devices with or without screens, SmartPerf provides two modes: SmartPerf-Device and SmartPerf-Daemon. 8 9- SmartPerf-Device is applicable to devices with screens and provides a visualized, intuitive UI that simplifies your operations. You can start and pause a test with a floating window, view performance data in real time, and save the test results for further analysis. 10- SmartPerf-Daemon is applicable to devices with and without screens and works with shell commands. 11 12The following are the available indicators: 13 14- CPU: The tool reads the frequencies and usage of CPU cores on the test device on a per second basis to measure the CPU usage of the target application. Sustained high CPU may lead to overheating. 15- GPU: The tool reads the GPU frequency and load information of the test device on a per second basis to measure the GPU usage of the target application. High GPU usage can lead to performance drops and application slowdowns. 16- FPS: The tool reads the frame rate, in frames per second (FPS), of the target application to measure the smoothness of the application image. A higher FPS generally means smoother visuals. 17- POWER: The tool reads the current and voltage of the test device on a per second basis. 18- TEMP: The tool reads the temperature information of the test device on a per second basis, including the battery temperature and system chip temperature. 19- RAM: The tool reads the RAM usage of the target application on a per second basis. 20- snapshot: The tool takes a screenshot of the application UI every second. 21 22## Principles 23 24The figure below demonstrates the main functions of SmartPerf. Set data collection items and parameters on SmartPerf-Device, start the application, and then send data requests for KPIs (such as FPS, RAM, and Trace) from SmartPerf-Device to SmartPerf-Daemon through messages. SmartPerf-Daemon collects, persists, and analyzes data as requested, and then sends the data to SmartPerf-Device for display. 25 26 27 28## Constraints 29 301. SmartPerf-Device and SmartPerf-Daemon are pre-installed since API version 9. 31 322. SmartPerf-Device can only be used on devices with a screen, and SmartPerf-Daemon must be connected to a hardware device. 33 343. Before using SmartPerf-Daemon, configure the [HDC environment](https://gitee.com/openharmony/developtools_hdc). 35 36## Performing Performance Testing 37 38### SmartPerf-Device 39 40The RK3568 development board is used as an example below. 41 421. Obtain the application list and select an application. 43 44Start SmartPerf-Device. On the home screen, select the target application. 45 462. Configure test settings. 47 48After the target application is selected, return to the start page and set the test indicators. You can also change the test name (which includes the name of the target application and the test time and will be displayed in the report), and specify whether to capture traces and whether to enable the screenshot feature. When you are done, click the start button at the bottom. 49 503. Use the floating window to manage data collection. 51 52To start collection, touch **Start** in the floating window. To pause, touch the timer in the floating window. To resume, touch the timer again. To view the collected data in real time, double-touch the timer. To stop, touch and hold the timer.<br>You can drag the floating window to anywhere you like. 53 544. View test results. 55 56Click **Report** to access the report list. Touch a report to view its details. 57 58### SmartPerf-Daemon 59 60**Basic Collection Commands** 61 62| Command | Function |Mandatory| 63| :-----| :--------------------- |:-----| 64| -N | Sets the number of collection times (once per second).|Yes| 65| -PKG | Sets the bundle name. | No| 66| -c | Collects the CPU frequency and usage. If the application bundle name is set, the collected information covers both the system and the target application.

The application bundle name must be specified. |No| 69| -profilerfps | Collects the frame rate of the current page. |No| 70| -t | Collects temperature information. |No| 71| -p | Collects current and voltage information. |No| 72| -r | Collects the RAM usage. If the application bundle name is set, the collected information covers both the system and the target application. If the application bundle name is not set, the collected information covers the system only. |No| 73| -snapshot | Takes screenshots. |No| 74| -net | Collects the network speed. |No| 75| -VIEW | Sets the view layer. You must obtain the layer name first. |No| 76| -screen | Collects the screen resolution and refresh rate. |No| 77| -d | Collects the DDR data. |No| 78| -m | Collects the process memory information. |No| 79| -sections| Sets segment-based collection. |No| 80 81 82**Commands for Starting or Stopping Data Collection** 83 84| Command | Function |Mandatory| 85| :-----| :--------------------- |:-----| 86| -start | Starts collection. This command can be followed by basic collection commands. |Yes| 87| -stop | Stops collection. A report is generated when collection is complete. |Yes| 88 89**Example** 90 911. Run the Win + R command to open the command-line interface (CLI). 92 93 ``` 94 C:\Users\issusser>hdc shell // Example 95 # 96 ``` 97 982.
