How does resource utilization compare between Piefed and Lemmy? (lemmy.zip)

I wanted to post this question in a neutral community and not the specific Lemmy or Piefed ones.

I am curious to learn how resource utilization is comparing in the real world operation of Piefed vs. Lemmy instances, given a similar level of users and user activity? Considering that Piefed is written in Python and Lemmy is written in Rust, I would think that the difference would be significant, but I recall someone mentioning in the past that the main resource constraint for both these platforms would be database-related instead so the language choice wouldn't have much impact. I'm curious if this is proving correct in the real world as opposed to in theory.

I know that there are a few admins out there who are running both and I would love to hear their thoughts on this.

Thanks. Do you know for how many concurrent users or any other measure of user demand?
