Postgres slowing factor

I'm pretty sure one of the best optimised free/libre DBMS's is faster than Python ๐Ÿ’€

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.

Yes, I also suspect that at a certain scale it would make a difference, but with a single Postgres database and no advanced clustering or so, the real-life performance metrics of a medium sized Lemmy instance strongly point to Postgres being the bottleneck and not the Python or Rust codebase of the rest of the software.
