What problem does it solve?
This Skill helps you deeply analyze CPU performance by leveraging hardware performance counters, enabling you to pinpoint bottlenecks related to cache, branches, and memory access.
Core Features & Use Cases
- PMU Event Collection: Gather specific hardware performance monitoring unit (PMU) events using
perf stat. - Metric Calculation: Compute key performance indicators like IPC, cache miss rates, and branch misprediction ratios.
- Source-Level Analysis: Correlate performance events directly to specific lines of source code using
perf annotate. - Use Case: Identify why a critical loop in your C++ application is running slower than expected by measuring L3 cache misses and branch mispredictions per instruction.
Quick Start
Use the hardware-counters skill to measure cache miss rate with perf.
