Actor pool components

I’m building an actor pool for ~300,00 actors. all of my actors will be the same class, but 1/100th of them will need optional sound components and 1/100 will have optional niagara effect components and 1/100 of them will need optional spotlight components.

Should I build seperate pools for actors with sound/niagara components, or would it be so little memory/performance difference that I can just have every actor have a sound and niagara component, with most of them being unused? Or would it be better to have a dedicated pool for sound/niagara actors and use them instead of components?
