For regular users there is not a huge difference, but the web-interface is significantly faster and you can subscribe to topics that combine multiple communities.
The really advantage is for moderators and admins, as the Piefed developers actually listened to community feedback and implemented a lot of nice moderation features that require bots or annoying work-arounds on Lemmy.
And there are a few technical differences that make Piefed easier to administrate and troubleshoot from a sysadmin perspective.

I’m pretty sure one of the best optimised free/libre DBMS’s is faster than Python 💀
Also no one know how Piefed scales, since it only has like 350 MAU

Reread it. They’re saying “The slowest part is postgres, so even if python is slower than rust it won’t make a difference.”

That is, in theory. In practice, it can make a big difference. Source: Worked professionally with large services built in Python and Rust.

Piefed also uses PostgreSQL. He was mentioning that the limiting factor on either platform is the DB, meaning the fact that the frontend that’s written in Python will not be a limiting factor.
Piefed also has quite impressive optimizations in other areas as well compared to Lemmy or even Mbin.
