Diffing very large objects takes seconds

[dbalatoni13]

My game uses unity build, so the objects are huge. Every time I want to check my changes, I have to wait seconds where the most time is spent diffing.

Maybe we could try to improve the speed in general or add a feature to re-diff only the function that's selected.

Here's a video of an object with a 0x39a90 bytes large text section:

Apropos: opening a function takes the same amount of time.
