We’re hosting an app on on Modulus.io with approx 11k concurrent sessions. When we deploy or restart our app, we see that the CPUs gets pinned at 100% for about 5 minutes. We can only speculate that this is because Meteor is reestablishing subscriptions/websocket connection with all the clients. During this time, no data loads in the app and it is unusable.
Has anyone experienced issues with high CPU on Meteor app bootup?
