Code Profiling

Gets familiar with profiling tools: perf, gprof, Valgrind. Runs basic profiling of system utilities, interprets simple flame graphs under mentor guidance.

Independently profiles system code: uses perf stat/record, callgrind, cachegrind. Finds hot paths in drivers, analyzes cache miss rate and branch misprediction.

Conducts deep profiling of kernel subsystems: uses ftrace, eBPF, perf probe. Analyzes latency distribution, identifies lock contention, optimizes critical kernel paths.

Defines profiling strategy for the systems team. Establishes continuous performance monitoring pipeline, automates performance regression testing.

Shapes enterprise approach to system software profiling. Defines performance KPIs for kernel subsystems, builds infrastructure for cross-platform performance analysis.
