@Rock DJ @verita84 I would love to run a Pleroma instance beside this Friendica - most software here runs on FPM-PHP. But my server is already low on RAM:
$ free
               total        used        free      shared  buff/cache   available
Mem:         7879800     4585788      313324      161140     3242464     3294012
Swap:        1995772     1995740          32
$

Yes, 8 GB RAM only. I may have time now, since I'm unemployed, to make the switch to a better server with 16 GB RAM and a bit cheaper, still with HDDs which I find more reliable than SSDs (Solid State Drive).

@Rock DJ @verita84 Yes, I remember now that Pleroma needs PostgreSQL . I wish software would have some better database abstraction, like #Doctrine2 under PHP or even #PDO is. Best would be like the #JPA (Java Persistence API) with JPQL (Java Persistence Query Language) where you query on entities and not tables. Its abstraction is very cool and you can theoretical replace both persistence and database at the same time with something other. For example EclipseLink is the reference implementation while there are other persistence providers like Hypernate (I cannot understand companies wanting this so much while the JPA is a much more flexible choice?). Then only theoretical you can replace at the same time MariaDB/MySQL with PostgreSQL (or even SQLite, there is a JDBC available) and else you have nothing else to touch.
