Abnormal surge of memory after upgrade elixir version to 1.15.6 on Heroku dyno

We are recently considering upgrade the elixir version from 1.8.1 to 1.15.6 as well as the phoenix framework. We tried it firstly in staging env and found that the memory usage increased dramatically: from 300M to 700M.

WX20231105-103037@2x
WX20231105-103037@2x930×326 24.9 KB

Use top command:

WX20231105-103227@2x
WX20231105-103227@2x1200×128 25.8 KB

I did some diagnosis by some tools such as observer_cli or just :erlang.memory() and found the amounts reported by these tools were far smaller than those from top command or Heroku metrics:

oc
oc690×484 57.9 KB

image
image1200×384 33.3 KB

So I am very confused about these numbers: which one is more credible? Or why they vary so sharply?
