+> from https://www.baeldung.com/java-async-profiler
+
+Enable Kernel configs:
+
+```shell
+sudo sh -c 'echo 1 >/proc/sys/kernel/perf_event_paranoid'
+sudo sh -c 'echo 0 >/proc/sys/kernel/kptr_restrict'
+```
+
+set `LD_LIBRARY_PATH` environment variable with async-profile build directory:
+
+```shell
+export LD_LIBRARY_PATH=/opt/async-profiler-2.9-linux-x64/build/
+```
+
+```shell
+./gradlew benchmarks:installDist
+```
+
+Run benchmark:
+
+```shell
