Solve the following python programming problem given the following code:
def TestJobQueueSubmissionPerformance() : 
    'PERFORMANCE: Job queue submission performance.

  This test exercises the job queue and verifies that the job submission time
  does not increase as more jobs are added.

  ' 
    MAX_CLUSTER_INFO_SECONDS = 15.0 
    job_driver = _JobQueueDriver () 
    submission_durations = [] 
    def _VerifySubmissionDuration(duration_seconds) : 
        if (len (submission_durations) >= 10) : 
            avg_duration = (sum (submission_durations) / len (submission_durations)) 
            max_duration = (avg_duration * 1.5) 
            if (duration_seconds > max_duration) : 
                print (qa_logging.FormatWarning (('Submitting a delay job took %f seconds, max %f expected' % (duration_seconds, max_duration)))) 
else : 
            submission_durations.append (duration_seconds) 
def _SubmitDelayJob(count) : 
        for _ in range (count) : 
            cmd = ['gnt-debug', 'delay', '--submit', '0.1'] 
            start = datetime.datetime.now () 
            job_id = _ExecuteJobSubmittingCmd (cmd) 
            duration_seconds = qa_utils.TimedeltaToTotalSeconds ((datetime.datetime.now () - start)) 
            _VerifySubmissionDuration (duration_seconds) 
            job_driver.AddJob (job_id) 
threads = qa_job_utils.QAThreadGroup () 
    for _ in range (10) : 
        thread = qa_job_utils.QAThread (_SubmitDelayJob, [20], { 
            
}) 
        threads.Start (thread) 
threads.JoinAndReraise () 
    qa_utils.AssertCommand (['gnt-cluster', 'info'], max_seconds = <MASK>) 
    job_driver.WaitForCompletion () 
    
    Given the code above, what is a proper replacement for <MASK>?
