Hi there, I’m a #devops person maintaining a Meteor application: https://github.com/unee-t/frontend/
Users have complained that they see performance slow downs. So I am wondering how to verify this, since from the ALB TargetResponseTime I see nothing untoward except for those people who are polling when the Web socket fails.
Is there some simple way for example to add User Time API? https://www.html5rocks.com/en/tutorials/webperformance/usertiming/
Any other quick tips for me (not a very good JS developer) to get my head around the problem and make users happier?
