1TB RAM Hertzner servers are available, so at least 8x more scaling before that's a problem.

2TB RAM is common in commodity servers, albeit expensive ones ($1000ish/month). Somewhere between 4TB to 20TB RAM is the pragmatic limit (where costs for vertical scaling start to get far worse)

Interestingly it seems max memories have been going down or at least not increasing in commodity x86 servers. Vendors advertised 24 TB servers enabled by lots of (192?) DIMM sockets in 2018 or maybe even earlier.

Is RAM still the limiting factor at that scale? Are you assuming 256 CPU cores?

Current theory is that Lemmy software is mostly RAM limited.

No one knows for sure until we reach those caps.
