Node running many POST requests at once

I want to make a bunch of post requests at once from my node.js script I have the same payload for every one of the requests and would want to simply spin them all off at once in some kind of loop and then make them write to a DB upon completion. Sample Code to demonstrate the logic:

for (var i = 0; i < 10; i++) {
    makePostRequest(updateDB);
}

function makePostRequest (callback) {
    http.post("test", function (result) {callback(result)});
}

function updateDB(result) {
    db.put({result: result});
}

The question is, is it better to do this using multithreading or does the fact that node will run these post request asynchronously take care of it and result in the same performance? In other words, will these post requests all happen asynchronously in a same way you would expect a multhreaded program behave and result in the same performance?

My goal is to minimize execution time.
