I'm trying to build the theme that is easily customizable by other developers and chose to go
get_template_part route so files can be easily overwritten in child theme.
My question is there some kind of limit for
get_template_part until it hurts performance?
For example, I'm using it for building a card UI, so each card has 5-10
get_template_part calls. If page displays 40 cards, that would be 400 disk lookups — could it hurt the performance? Is it better to move to regular functions (e.g. template tags)?
