Tab Container memory usage

I’d like to use tab container for my plant which include 20 P&ID pages. Other method is to use horizantal menu item with 20 separate Page configuration for each P&ID diagram. If I want to compare tab container with ‘menu item + separate page’ which one is more memory efficient and easier for browser to render?

The Tab Container is going to be more efficient, but not by very much. I would still recommend the Horizontal Menu if for no other reason than the fact that the “tabs” of the Horizontal Menu will Flex to accommodate longer text items. The Horizontal menu has a fixed tab width which is the same for all of the tabs.
