Hey Ampere Developers,

**How do Performance Engineers characterize and fix performance issues?**

Have you ever wondered how application performance engineers go about finding that needle in a haystack when a customer comes to them with a performance issue? How do you go from “My application is running slower than I expect” to understanding exactly what the issue is, and fixing or working around it?

In this video, the first of a series on the Ampere performance toolkit, Bhakti Hinduja breaks down exactly how top-down performance analysis works, starting with reproducing a performance issue with a synthetic benchmark, understanding which subsystem is constraining the performance in the “bad” case, and finally drilling down to identify the root cause.

```

In part two of the series, Bhakti explores the individual tools in the Ampere Performance Toolkit, and digs a little deeper into the types of problems solved by each of them:

The Ampere Performance Toolkit makes it easy to perform each of these steps, accelerating your ability to understand your own system performance, including:

- Capturing system configuration and benchmark results with the Ampere Perfkit Benchmarker: [GitHub - AmpereComputing/ampere-perfkit-benchmarker · GitHub](https://github.com/AmpereComputing/ampere-perfkit-benchmarker)
- Analyzing system performance to identify bottlenecks with the Ampere System Profiler: [GitHub - AmpereComputing/ampere-system-profiler · GitHub](https://github.com/AmpereComputing/ampere-system-profiler)
- Drilling down to CPU measurements to understand how CPU cores are spending their time with the Ampere PMU Profiler: [GitHub - AmpereComputing/ampere-pmu-profiler: Performance characterization and analysis tool for Ampere CPUs · GitHub](https://github.com/AmpereComputing/ampere-pmu-profiler)

Stay tuned as we publish much more content and use-cases of people seeing benefit from using these tools!
