High RAM usage

[lnlyssg]

I'm not sure if this is expected but doku seems to use a lot of memory. I couldn't find any issues for this but it seems to be fairly high no matter the machine, I'm running it on four different Ubuntu servers and it's using at least 1GB on all of them. See below collected docker stats output for each of these machines:

CONTAINER ID   NAME                    CPU %     MEM USAGE / LIMIT     MEM %     NET I/O           BLOCK I/O         PIDS
774965304f80   doku                    0.13%     2.11GiB / 15.49GiB    13.62%    232kB / 2.08MB    327GB / 4.16GB    14

My compose file is fairly basic:

  doku:
    image: amerkurev/doku:latest
    container_name: doku
    restart: unless-stopped
    ports:
      - 9090:9090
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /:/hostroot:ro
