Records in saga_entry removed slowly

Hi, there is a problem confusing me, I used saga to deal with some events, but I found that the velocity of saga is low, about 6 events be dealt with in one minute. So, what can I do to improve the speed of saga?

My code like this:

@Saga(sagaStore="")
public class someGaga{
   
   @StartSaga
   @SagaEventHandler
   public void handle(AEvent event){
      ACmd cmd = contert2Cmd(event);
      commandGateway.sendAndWait(cmd);
   }

   @EndSaga
   @SagaEventHandler
   public void handle(BEvent event){
      BCmd cmd = contert2Cmd(event);
      commandGateway.sendAndWait(cmd);
    }
}

The records in the table named saga_entry be removed slowly, how to make it faster?

Have you tried adding some indexes on the table AssociationValueEntry ?
