The notebook-environment configuration should in general produce better, more fine-grained results because it can do things like cull unused kernels and be aware of things like idle/busy or connected status. This lets the notebook server make more intelligent choices like “shutdown a kernel if it’s been idle for 5 minutes BUT not if…
