@Breadly currently 1.1G RAM usage for #Pleroma 61G RAM for #PostgreSQL. My instance is 7 years old and running on bare metal hardware. I have tuned #PostgreSQL for performance there.

for multi-user #Pleroma and #Peertube instance #Postgres (v13) uses 3.8G RAM, #PostgreSQL (v15) uses 42M RAM, i need to migrate shit i think. #Pleroma uses 3.8G and #Peertube uses 300M, instance is also on a similar bare metal hardware, but it's much much younger.
