Looks quite light to me:

$ ps -o pid,vsz,rss,start,command `pidof dbus-daemon`
   PID    VSZ   RSS  STARTED COMMAND
   861  31284  2032   Dec 08 /bin/dbus-daemon --system --address=systemd: --
nofork --systemd-activation
  1019  33188  2196   Dec 08 /bin/dbus-daemon --fork --print-pid 5 --print-
address 7 --session

What are your main issues? What happened to your case?
