23 * saving at the cost of lower sampling rate and higher software overhead.

11 The sampling interface provides API to measure and get count for specific perf events.
13 The following test tries to explain count on `sampling.c` example.
15 It is by no means complete guide to sampling, but shows libperf basic API for sampling.
17 The `sampling.c` comes with libperf package and can be compiled and run like:
21 $ gcc -o sampling sampling.c -lperf
22 $ sudo ./sampling
36 The `sampling.c` example profiles/samples all CPUs with hardware cycles, in a
