What specs for a self-hosted Lemmy instance? (aussie.zone)

Hi all, a shout-out for assistance. I’m considering hosting a Lemmy instance (assuming I can pass the wife test on costs) and I’m looking for some guidance on specs.

Can anyone who’s currently hosting an instance (or who knows the inner workings of one) please reply with:

specs on the hardware / VPS that’s hosting your instance
how many users / posts that’s supporting
what the system load looks like with the above
if locally hosting, the type of bandwidth requirements you’re seeing

I previously posted this in the wrong community, and one of the responses asked how many users I'm expecting. To preemptively answer - I don't know. I'm just trying to get an idea of relative sizing.

Thank you!!

I'm running my instance as a containerized app on an i9-12900H, 64gb ddr4 ram, a 128gb Intel optane as a swap drive (my mobo maxes out at 64gb ram), and on a SATA SSD. My bottleneck is my internet which is stuck on 5g home internet. Serving. Any service behind cgnat has been a challenge, but thanks to zero tier and a vps reverse proxy, it's been possible.

Interesting, does it actually help when your system run out of memory? My system is completely unusable when it starts swapping at one time (some app was leaking memory and exhaust the ram), so I decided to turn off the swap (I'd rather it crashed than have unusable system).

It won't replace RAM speeds, but it's supposed to be significantly faster. Caveat is that it's not functioning like optane memory is supposed to, I just opted to make the whole drive partition swap, since it was simpler to do.

I never have used a significant amount of my RAM to warrant heavy swap usage though. Swappiness is at its default 60.
