--debug-file
Write debug output to a specified file.
Performance counters for Linux are a new kernel-based subsystem
that provide a framework for all things performance analysis. It
covers hardware level (CPU/PMU, Performance Monitoring Unit)
features and software features (software counters, tracepoints)
as well.
