Object pools and static objects

It’s been a couple years since this was last discussed and I didn’t see an official unity answer...

I dynamically generate my world by putting mesh objects in an object pool then activating them at various places as the player moved. So they don’t move while active, but they do get placed, activated, deactivated, and re-used elsewhere (infinite runner style)

So, for draw optimization should they be marked static or no?

 

It's new to me, that Unity allows to mark objects as static during run-time. As far as I know, "static flags" is available in the editor only and various optimization techniques are applied to static objects while Unity is creating a build/player, not during run-time.

In terms of optimizations, I recommend to use the Profiler to measure both cases on the particular target hardware. This will definitely give you an answer what's faster.
