can you benchmark the performance delta between MVC 5.2 and the new CORE 7.x?

if i have grid with 2000 elements, by grouping and not grouping with some serious renderers (colors. background colors, etc).

If i have a complex page with 20 different forms, then i have a combo (with the name of each form) so i can select from the combo and that form shows and the rest hide.

what is the performance delta to load these pages? i would love to see a benchmark analysis.

Also, even though not all examples exist yet and that is super important, will everything work if we upgrade?
