Postgres slowing factor

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

EDIT: skimmed it wrongly, see corrections below

Also no one knows how Piefed scales, since it only has like 350 MAU

Piefed also uses PostgreSQL. He was mentioning that the limiting factor on either platform is the DB, meaning that the parts written in Python will likely not be a limiting factor.

Piefed also has quite impressive optimizations in other areas as well compared to Lemmy or even Mbin.

CSRF protection is a security feature not bot prevention. A bot would just need to get a token first.

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

Ya gotta give a line from it or something, I don't just see numbers and know what they are.

No, just punk.

I don't think so, I will definitely go back and do not wish to move permanently in another instance.

As others have said I think this instance has a strong base of dedicated users, it's a "specialized" instance that has no equivalent.

from context, it's probably the "single dude in nebraska holding up the entire internet" one

e: holy shit I got the state right

Is it run out of a private residence? How could it happen if it’s in a real data center…?

It is run from a private residence in the DIY punk spririt (and this also allows us to run of a local solar PV system), but more or less the same would happen if you rent rack-space in a "real" data-center. Only if you rent a managed server or VPS someone else will be responsible to fix such issue and this comes at a significantly higher cost at the scale we operate at (slrpnk is part of a bigger project that also hosts other services).

If you rent rack space, you can at least call the DC to send someone to reboot it or smt.

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

Sure, but they will not replace hardware and set up remote access for you, which seems like this would have been required in this case.

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 disadvantage is less mobile app support. Right now only Interstellar supports Piefed.

The real 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.

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.

"unforseen hardware failure"

somebody didn't check their backups!

The backups are most likely fine

yes, that's why it's been down for this long...

Slrpnk.net is unexpectatly back online 🥳
