FAQs

What is Arm Performix?

Arm Performix is Arm’s performance profiling and analysis toolkit for developers building and running performance-critical workloads on Arm-based systems. It profiles running applications, collects system- and hardware-level metrics, and translates them into guided insights that help identify CPU, memory, and system bottlenecks.

Arm Performix supports large-scale cloud, infrastructure, and AI workloads on Arm platforms including AWS Graviton, Microsoft Cobalt, Google Axion, and next-generation Arm solutions.

Who is Arm Performix designed for?

Arm Performix is built for engineers responsible for validating, profiling, and optimizing workloads on Arm across development, deployment, and production:

  • System and Platform Engineers – platform bring-up, firmware, kernel, hardware validation
  • Core Library Developers – C/C++, SIMD/vectorization, performance-critical primitives
  • Runtime and Compiler Engineers – JITs, toolchains, AI frameworks, distributed runtimes
  • Cloud and Backend Developers – hyperscale services, SaaS platforms, CI/CD regression monitoring
What problems does Arm Performix solve?

Arm Performix reduces root cause analysis time from hours to minutes and lowers the barrier to production-grade performance optimization on Arm.

  • Multi-core, NUMA, and heterogeneous compute architectures
  • Performance interactions across CPU, memory, networking, and storage
  • OS-level, hardware-level, and application-level behavior
How does Arm Performix work?

With a single command, Arm Performix performs application and system profiling on Arm-based servers. Connecting to a local, on-prem, or cloud-based Arm system. It also:

  • Profiles a running workload
  • Collects system-level and application-level performance counter data
  • Identifies bottlenecks across compute, memory bandwidth, and core utilization
  • Provides guided next steps for optimization

Rather than exposing raw counters alone, Arm Performix explains what metrics mean and why they matter, enabling faster, more confident optimization decisions.

What platforms and environments are supported?

Arm Performix supports Arm Neoverse-based systems running Linux, including cloud environments such as AWS Graviton, Microsoft Cobalt, Google Axion, and next-generation Arm solutions. It is designed for both on-premises data center deployments and large-scale public cloud infrastructure.

How can I access Arm Performix? Is there a fee?

Arm Performix is free to download and use, so you can start analyzing and optimizing performance right away.

Can Arm Performix be integrated into CI/CD pipelines?

Yes. Arm Performix produces machine-readable output suitable for automation and regression tracking. Engineering teams can integrate it into CI/CD pipelines to:

  • Detect performance regressions early
  • Track optimization impact over time
  • Compare performance across architectures
  • Validate scaling characteristics before production rollout

This makes continuous performance validation a standard part of cloud-native development workflows.

What level of expertise do I need to use Arm Performix?

Arm Performix is designed to be accessible to all engineers without requiring deep Arm microarchitecture knowledge. It provides guided, architecture-aware insights that contextualize performance data and highlight root causes directly.

How is Arm Performix different from traditional performance tools?

Traditional CPU profiling and performance analysis tools often expose raw hardware counters without guidance. Arm Performix differs by providing:

  • A unified data collection and analysis workflow
  • Cross-layer visibility (system and application)
  • Bottleneck identification across compute and memory subsystems
  • Actionable, architecture-aware recommendations
  • Automation-ready outputs

It eliminates tool-hopping and manual counter interpretation, delivering production-ready performance insight tailored specifically for Arm environments.

How does Arm Performix support AI and cloud optimization?

For AI inference services, distributed runtimes, and large-scale backend systems, performance efficiency directly impacts infrastructure cost, fleet sizing, and power consumption.

Arm Performix helps teams profile AI inference workloads and cloud services running on Arm infrastructure by:

  • Validating workload scaling characteristics
  • Optimizing memory bandwidth utilization
  • Identifying CPU bottlenecks in inference pipelines
  • Increasing confidence in workloads migrated to Arm from X86

This ensures performance transparency across modern AI and cloud deployments.
