Slow meteor update



I was playing around with meteor and built a small prototype for my app. However, when I made updates to my mongo database, the updates took ~4-5 seconds to reflect on the web page. The collections are really small (~500 documents max). Is this normal? Also, I am running my meteor app and mongo db instance in 2 different docker containers. I wonder if that is what is slowing things down?


Make sure that you have Mongo Oplog tailing enabled. This is what Meteor uses for data updates and if it is not available it falls back to polling every 3-5 seconds.


You’re correct. I had to setup a replica set and then provide meteor with the oplog url for it to work. Thanks!
