### Who is this for?
This is an introductory topic for software developers who want to learn performance analysis methodologies for Linux applications on Arm Neoverse-based servers.

### What will you learn?
After completing this Learning Path, you'll be able to perform the following tasks:
- Identify CPU pipeline bottlenecks using the Arm Performix CPU Microarchitecture recipe
- Analyze instruction types and SIMD utilization using the Instruction Mix recipe
- Optimize application performance using vectorization and compiler flags
- Compare performance profiles to measure execution improvements

### Prerequisites
Before starting, you'll need the following prerequisites:
- An Arm Neoverse-based server running Linux, such as an Arm AGI CPU platform.
- Bare-metal server or cloud bare-metal access is preferred for hardware performance counters
- Familiarity with Linux command line
- Basic understanding of CPU performance concepts
