Q. Firebase cloud functions is very slow
^When your function hasn't been executed in some time, Cloud Functions puts it
in a mode that uses fewer resources. Then when you hit the function again, it
restores the environment from this mode. The time it takes to restore consists of
a fixed cost (e.g. restore the container) and a part variable cost (e.g. if you use a lot
of node modules, it may take longer). ̄
