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
18To show assembler sample contexts use perf record -b / perf script -F +brstackinsn --xed
19Treat branches as callchains: perf report --branch-history
20To count events in every 1000 msec: perf stat -I 1000
21Print event counts in CSV format with: perf stat -x,
22If you have debuginfo enabled, try: perf report -s sym,srcline
23For memory address profiling, try: perf mem record / perf mem report
24For tracepoint events, try: perf report -s trace_fields
25To record callchains for each sample: perf record -g
26To record every process run by a user: perf record -u <user>
27Skip collecting build-id when recording: perf record -B
28To change sampling frequency to 100 Hz: perf record -F 100
29See assembly instructions with percentage: perf annotate <symbol>
30If you prefer Intel style assembly, try: perf annotate -M intel
31For hierarchical output, try: perf report --hierarchy
32Order by the overhead of source file name and line number: perf report -s srcline
33System-wide collection from all CPUs: perf record -a
34Show current config key-value pairs: perf config --list
35Show user configuration overrides: perf config --user --list
36To add Node.js USDT(User-Level Statically Defined Tracing): perf buildid-cache --add `which node`
37To report cacheline events from previous recording: perf c2c report
38To browse sample contexts use perf report --sample 10 and select in context menu
39To separate samples by time use perf report --sort time,overhead,sym
40To set sample time separation other than 100ms with --sort time use --time-quantum
41Add -I to perf record to sample register values, which will be visible in perf report sample context.
42To show IPC for sampling periods use perf record -e '{cycles,instructions}:S' and then browse context
43To show context switches in perf report sample context add --switch-events to perf record.
