Prefs
   1For a higher level overview, try: perf report --sort comm,dso
   2Sample related events with: perf record -e '{cycles,instructions}:S'
   3Compare performance results with: perf diff [<old file> <new file>]
   4Boolean options have negative forms, e.g.: perf report --no-children
   5Customize output of perf script with: perf script -F event,ip,sym
   6Generate a script for your data: perf script -g <lang>
   7Save output of perf stat using: perf stat record <target workload>
   8Create an archive with symtabs to analyse on other machine: perf archive
   9Search options using a keyword: perf report -h <keyword>
  10Use parent filter to see specific call path: perf report -p <regex>
  11List events using substring match: perf list <keyword>
  12To see list of saved events and attributes: perf evlist -v
  13Use --symfs <dir> if your symbol files are in non-standard locations
  14To see callchains in a more compact form: perf report -g folded
  15Show individual samples with: perf script
  16Limit to show entries above 5% only: perf report --percent-limit 5
  17Profiling branch (mis)predictions with: perf record -b / perf report
  18Treat branches as callchains: perf report --branch-history
  19To count events in every 1000 msec: perf stat -I 1000
  20Print event counts in CSV format with: perf stat -x,
  21If you have debuginfo enabled, try: perf report -s sym,srcline
  22For memory address profiling, try: perf mem record / perf mem report
  23For tracepoint events, try: perf report -s trace_fields
  24To record callchains for each sample: perf record -g
  25To record every process run by a user: perf record -u <user>
  26Skip collecting build-id when recording: perf record -B
  27To change sampling frequency to 100 Hz: perf record -F 100
  28See assembly instructions with percentage: perf annotate <symbol>
  29If you prefer Intel style assembly, try: perf annotate -M intel
  30For hierarchical output, try: perf report --hierarchy
  31Order by the overhead of source file name and line number: perf report -s srcline
  32System-wide collection from all CPUs: perf record -a
  33Show current config key-value pairs: perf config --list
  34Show user configuration overrides: perf config --user --list
  35To add Node.js USDT(User-Level Statically Defined Tracing): perf buildid-cache --add `which node`
  36To report cacheline events from previous recording: perf c2c report
