Update takes ~20 minutes and progress update breaks (temporarily) at step multisite:migrate

Ok, thanks! I wasn’t aware that DB tuning would be required (we’re using the single container setup) and there’s not much else running on the machine (Discourse, Mailcow, Traefik, Crowdsec). But I’ll have a closer look.
Any pointers to relevant documentation in this regard? The only thing I’m aware of right now is Configure Discourse Docker on servers with more RAM and CPU, and our db_shared_buffers is already at 4096MB.
