I am still not sure how to make that change and build the kolibri application to be installed on an ubuntu instance.
For testing purposes: I created a new postgres DB using the same data that we have in production and also created a new ec2 instance that is running kolibri-server.
I tried loading the coach’s tab for running reports, and it still took a long time to load (it didn’t crash though as it would in production). So, can we assume that a big number of concurrent users on kolibri has too little effect on performance?
