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 currently hosting an instance for about 20 users on a dual-core epyc-7002 based cloud vm with 2 gb of ram and currently a 50 gb ssd volume. memory tends to sit around halfway and total disk usage is 14 GB, of which it's 4.5 GB for the picture server and 2.3 GB for the database for now, i'm monitoring both in case upgrades are needed. cpu usage is quite low, usually sits between 5-10% and never went above 25%. it was the highest during a spambot attack when they tried to register hundreds of accounts -- speaking of, enable captcha (broken on 0.18.0) or set registrations to approve-only.

i'm paying about $10-15 per month currently, which includes a cache to keep the instance snappy.
