And to run, execute the following if you want a `JFR` file which can be analyzed with Java Mission Control:
```shell
profiler.sh collect -d 60 --jfrsync ${JAVA_HOME}/lib/jfr/default.jfc -f profile.jfr Worker
asprof collect -d 60 --jfrsync ${JAVA_HOME}/lib/jfr/default.jfc -f profile.jfr Worker
```

Use the following for more accurate profiling:
```shell
profiler.sh collect -d 60 --jfrsync ${JAVA_HOME}/lib/jfr/default.jfc -e cycles --cstack lbr -f profile.jfr Worker
asprof collect -d 60 --jfrsync ${JAVA_HOME}/lib/jfr/default.jfc -e cycles --cstack lbr -f profile.jfr Worker
```

Or use the following if you do not care for a jfr file but want a flamegraph directly:
```shell
profiler.sh collect -d 60 -f flamegraph.html Worker
asprof collect -d 60 -f flamegraph.html Worker
```
