perf

Framework for Linux performance counter measurements. More information: https://perf.wiki.kernel.org.

  • Display basic performance counter stats for a command:

perf stat {{gcc hello.c}}

  • Display system-wide real-time performance counter profile:

sudo perf top

  • Run a command and record its profile into perf.data:

sudo perf record {{command}}

  • Record the profile of an existing process into perf.data:

sudo perf record {{[-p|--pid]}} {{pid}}

  • Read perf.data (created by perf record) and display the profile:

sudo perf report
