Performance Profiling and Optimization on Arm Neoverse CPUs

Arm Streamline CLI Tools help uncover sources of performance problems on Arm Neoverse systems, linked back to functions in source code or dependencies. Designed for performance-sensitive applications and libraries written in C, C++, Rust, and Go, developers can use the Streamline profiler to optimize database technology, web servers, and interpreter runtimes to optimize performance on the Arm architecture.

Features and Benefits

Targeted Feedback on Software Performance 

Profiling workloads on Neoverse presents high-level metrics categorized according to key phases of CPU behavior. These metrics help you to ensure your code is efficiently utilizing the hardware, and where your software algorithms could reduce redundant processing or use vectorization.

Deployment to Cloud Infrastructure

Deploy profiling tools directly to the cloud to sample performance during testing. The Streamline tool uses efficient sampling to reduce the volume of data needed to support attribution of performance to functions in code.

Integrate and Analyze Metrics on the Cloud

Captured data is analyzed on the server and summarized into easy-to-use performance reports, making further local analysis on the development machine simple and lightweight. Visualize the output or integrate the data into custom monitoring workflows.
