Canvas component has over 100 controls

Hello community, I'm building canvas component which contains over 100 button controls and use it for other screens ( Since it has to be unique and random, i can't use gallery for this ). From app performance perspective, I know components would counted as 1 control when running and that's why I'm creating component for this case. Just wanted to know if there is any person have similar case? Using this type of component is really effective for performance side even it has over 100 controls inside?
