so i have to make rubycache the same configuration as Ruby ? because it seems that every cache access is checked to make sure it behaves (miss/hit) the same in rubycache and Ruby.

Opal's rubycache is only meaniful in uniprocessor target systems, as it
doesn't do any cache coherence. Even then I would recommend running with
Ruby to simulate that target system, as it has more accurate memory
timings.

No.
