app.js

var stream = require('getstream');
client = stream.connect('key', 'secret', 'id', { location: 'eu-central' });

var feed = client.feed('user', 'foobar');
var counter = 20;
var results = [];
function fetchFeed() {
  var start = new Date().getTime();
  feed.get({limit:20}).then(function(data) {
    results.push(new Date().getTime() - start);
    process.stdout.write(".");
    if (counter-- > 0)
      fetchFeed();
    else
      console.log((results.reduce(function(a, b) { return a + b; }) / results.length) + "ms");
  });
}

fetchFeed();

Cool! Great job identifying the issue so fast!
