Document performance of deterministic vs non-deterministic

[punkpeye]

I am assuming that setting { deterministic: true } has performance implications, vs just using { deterministic: false }.

It would be good to know how measurable those are.

When I checked it last time, it didn't have a real impact on regular use cases. It will however always depend on the input. In case objects have a lot of properties that are completely unsorted, it's going to require more work.

Would you be up to do a few tests and open a PR to add a small comment with the outcome? That would be highly appreciated :)
