@Vivek1106-04 I got a good idea about 2 using my chatgpt
I agree with the first option in point 2: use the minimum valid
`checkpointInterval` of 10 ms and set `checkpointMinPause` to `-1`.
The 10 ms interval can be isolated from the JMH result through
invocation-level setup:
```java
@Setup(Level.Invocation)
public void prepareInvocation() throws Exception {
awaitPreviousCheckpointCompleted();
// Cancel only the measured coordinator's automatically re-armed task.
cancelMeasuredCoordinatorTasks();
// Outside the measured region.
TimeUnit.MILLISECONDS.sleep(11);
// Arm the task-specific probe after the fixture is quiescent.
probe.arm();
}
```
JMH does not include `@Setup(Level.Invocation)` in the measured operation
time.
The measured region remains:
```text
scheduleTriggerPendingCheckpoint
→ real scheduler
→ tryTriggerPendingCheckpoint
→ state checks
→ coordinator lock
→ submission to executorService
```
The previous checkpoint completion, timer cleanup, and 10 ms interval wait
remain outside the measured result. Background coordinators can continue
running normally to preserve multi-pipeline scheduling load.
