Collections vs Tab Groups

[domnorko]

Is tab groups, or collections more energy efficient (ram, memory, overall edge performance) for open tabs? Just wondering the difference it makes to keep all my open tabs in a tab group vs. a collection. Sleeping tabs is turned on.

I have noticed that adding a lot of tabs to a collection slows down edge and even freezes it. Sync seems to struggle with large tab collections also. For optimal performance, curious if moving them all to a tab group uses less energy/memory. Or if I should do neither and keep them in their vertical list.
