Calculation question regarding when measures are processed -specifically related to slicer selection

I'm curious to know if measures which are not used on a particular tab calculate when a slicer selection is made. When a slicer selection is made, every visual and measure on the tab appears to render the requested filter selection (as expected). What I want to know is if having dormant measures in a Power BI file is causing possible performance issues because they're recalculating upon a slicer selection even if they're not used in the report.

To provide more context, these 'dormant' measures are calculations that might be used in the future which is why I'm hesitant to delete them unless they're actually a contributor to the performance issues I'm facing.

I'm totally aware performance issues go far and beyond measure calculations, but the data is clean as possible, so I want to explore the question I posed.

Thanks!
