Performance Profiling

Analyze system and application performance using comprehensive profiling techniques including Linux kernel-level tools (perf, ftrace, eBPF, SystemTap), application-level profiling, bottleneck identification, and optimization recommendations to improve system responsiveness, throughput, and resource efficiency.

When to use me

Use this skill when:

• Application performance is slow or degrading
• System resource utilization is high
• Identifying CPU, memory, I/O, or network bottlenecks
• Optimizing application response times
• Debugging performance regressions
• Capacity planning and resource sizing
• Comparing performance before/after changes
• Analyzing production performance issues
• Creating performance baselines
• Tuning system and application parameters
