I am using the official low level node.js api(https://github.com/GetStream/stream-js). Every get request delays between 800ms and 1300ms. even tough I am located in Argentina and using the free plan i know that is not normal. My app is in the region us-east, here is a little snippet of my code:
function getFeed(userId, lang, lastId){
logger.error("get user feed for: " + userId + ", lang: " + lang);
userFeed = client.feed('timeline', lang+userId);
var restrictions = [{limit:10}];
if(lastId)
restrictions.push({id_lt: lastId});
return userFeed.get(restrictions); //returns promise
}
