    Update statistics that allows the driver to determine if a query is slow enough to be logged, and return the estimation result for millisOrNanos value.
    Used in case autoSlowLog=true.
    
    参数:
    
    millisOrNanos - query execution time
    
    返回:
    
    true if millisOrNanos is outside the 99th percentile?
