How about renaming it to `TaskProcessRateCalculator`? And then, we can also rename the function `maySpeculateTask` to `isEfficient`. `checkAndSubmitSpeculatableTasks` can decide whether to speculate the task depending on the return value of `isEfficient`. As a result, `TaskProcessRateCalculator` only foucs on task progress rate and no specualtive stuff. -- This is an automated message from the Apache Git Service.
