I think I have figured it out myself somehow.
The issue of inserting of million of data from Nodejs into MongoDB is that, nodejs is so occupied by generating those records and send them out immediately. All the million of data appear immediately, and nodejs itself got stucked after a while, and at this moment MongoDB does not receive much incoming insert yet. 
I "get rid of" this problem by setting a interval method which insert 10000 records at one time, and recall this interval every second, so that nodejs get the chance to move to its next 
event to send the generated inserts out, and then start the generation of inserts again.
interval_checkId = setInterval(createSomeInsert, 1000);

And the createSomeInsert method:
function createSomeInsert() {

    console.log("* Starting to insert another 10K records, current count: " + counter);

    var collection = dbPool.collection('gm_std_measurements_coveringindex');

    var date = new Date();
    var amount = 10 * 1000;
    for(var i = 0; i < amount; i++) {

        var ranNumber = Math.floor((Math.random() * 1000) + 1);

        // insert objects after table and index creation
        var istObject = {
            fkDataSeriesId : ranNumber,
            measDateUtc : date,
            measDateSite : date,
            project_id : ranNumber,
            measvalue : ranNumber,
            refMeas : false,
            reliability : 1.0
        };

        collection.insert(istObject, { w : 0 }, function(err, docs){
            if(err) {console.log(err); throw err;}
            counter++;
        });

    }

    if(counter >= totalTarget) {
        clearInterval(interval_checkId);
        console.log("Completed Insert, in total : " + counter);
        counter = 0;
    }
}

However, I still do not understand why nodejs will be blocked after many insert requests have been generated, and why most of them are not sent to mongodb in the background.

 The issue of inserting of million of datum from Nodejs into MongoDB is that, nodejs is therefore occupied by generating those record and transport them out immediately. All the million of data appear immediately, and nodejs itself got stucked after a while, and at this consequence MongoDB does not meet much incoming insert so far. 
 I " get rid of " this problem by set a interval method acting which insert 10000 records at one time, and recall this interval every second, so that nodejs get the chance to travel to its next 
 event to send the generated cut-in out, and then start the generation of inserts again. 
 interval_checkId = setInterval(createSomeInsert, 1000); 

 And the createSomeInsert method: 
 serve createSomeInsert () { 

     console.log (" * Starting to insert another 10 K records, current count: " + counter); 

     var solicitation = dbPool.collection('gm_std_measurements_coveringindex'); 

     var date = new Date ();

     for(var i = 0; i < amount; i++) { 

         var ranNumber = Math.floor((Math.random () * 1000) + 1); 

         // insert objects after mesa and index creation 
         var istObject = {

         collection.insert(istObject, { w: 0 }, function(err, docs) {

         console.log("Completed Insert, in total: " + counter); 
         counter = 0;

 } 

 However, I still do not sympathize why nodejs will be stuff after many insert requests have been beget, and why most of them are not mail to mongodb in the background.
