Profiler overview

The Unity Profiler is a tool you can use to get performance information about your application. You can connect it to devices on your network or devices connected to your machine to test how your application runs on your intended release platform. You can also run it in the Editor to get an overview of resource allocation while you’re developing your application.

The Profiler gathers and displays data on the performance of your application in areas such as the CPU, memory, renderer, and audio. It’s a useful tool to identify areas for performance improvement in your application, and iterate on those areas. You can pinpoint things like how your code, Assets, Scene settings, camera rendering, and build settings affect your application’s performance. It displays the results in a series of charts, so you can visualize where spikes in your application’s performance happen.

In addition to using the built-in Unity Profiler, you can use the low level native plug-in Profiler API to export profiling data to third-party profiling tools, and the Profiling Core package to customize your profiling analysis. You can also add powerful profiling tools such as the Memory Profiler, and the Profile Analyzer to your project to analyze performance data in further detail.

To access the Profiler window go to menu: Window > Analysis > Profiler. For a detailed overview of the window, see the Profiler window documentation.
