mongoose w/ bluebird promise performance test

gistfile1.txt

mongoose schema:

update: function(row){
    return this.update({}, row).exec();
}

// method 1
batchUpdate: function(rows){
    return Promise.map(rows, function(row){
        return self.update({}, row).exec();
    });
}

another js:

// method 2
return Promise.map(rows, function(row){
    return model.update(row);
});

// method 1 is twice faster than method 2
