Slow Starting Time

Hi, sorry if this has been discussed before, but I wanted to know if I can improve the starting time of my Phoenix app. For reference, I am running a lightweight Phoenix web app on one node and another node running Fly Postgres (both are shared-cpu-1x:1024MB). Both nodes are running in the same region close to me.

The web app has auto start/stop enabled, and has high response times when the node is running. However, when navigating to web app when the node is down (after it automatically shuts down), it takes ~3-4 seconds to load the page for the first time. Is this normal times for Phoenix, or is there something wrong? I dont see anything out of ordinary in logs, but here they are just in case (when navigating to web app when its down) -
