How set a wait between severals sendRequest to avoid collapse the server

Hi. First of all, no, I will not ask about synchronous requests o sequential

I am making a loop where within it I generate differents object and send it through pm.sendRequest (). The problem is that when the array is very large I saturate my server. I have tried several methods (below you will see it) but it is not respecting the wait (I observe it from Kibana).

var maritalStatus = ['single', 'married', 'divorced', 'not indicated']
var obj = {"status" : "aux"}

function timeOut (milliseconds){
   setTimeOut(() => {
   }, milliseconds);

for (const i in maritalStatus){
      obj.status = maritalStatus[i]
      function timeOut(2000); //<- The wait

        url: 'https://',
        method: 'POST',
        header: { 'Content-Type': 'application/json' },
        body: {
            mode: 'raw',
            raw: obj
    }, function (err, response) {
        if (err) {
        } else {

In the Postman´s console I observe that the internal requests (sendRequest ()) are painted first and then the “waiting” logs. I observe in Kibana that the requests have arrived with a difference of thousands of seconds not with at least two seconds.

Another way of waiting that I tried to try but it didn’t work.

function wait (millis){
var t = new Date().getTime();
while (new Date().getTime()< t+millis);

In my example I have put a simple case but in reality hundreds of Postman´s requests execute thousands of SendRequest().

Any ideas?

@vcardenas What you can do is call the postman-echo delay endpoint.

You can add this:

// This will basically halt the script for 3 seconds.. 
// It can delay from 0 to 10, with 10 being the max delay.
