Arm Performix

About

Arm Performix is a performance analysis toolkit for server and cloud developers building on Arm-based infrastructure, including Arm Neoverse platforms such as AWS Graviton, Microsoft Cobalt, and Google Axion. It provides function-level insights, visualizations, and guided recommendations derived from hardware-level execution data, helping teams understand and optimize software performance on Arm. The site describes it as making performance analysis accessible, repeatable, and automatable for cloud native software and agentic workflows.

Arm Performix is aimed at cloud backend and application developers, platform and system software teams, core library and framework developers, and performance and infrastructure engineers. According to the site, it helps users find hotspots in complex applications, understand why performance is limited, and focus optimization effort where it matters, without requiring deep expertise in CPU microarchitecture. It is available as a full toolkit with UI and CLI, or as the CLI alone, with builds for Mac, Windows, and Linux.

The toolkit can be run from the command line, integrated into CI/CD pipelines, and accessed within development environments, including through the Arm MCP Server with a developer's preferred editor. The site also points to learning paths, a user guide, code-alongs, and open source source code for further learning.
