I adjusted two parameters:

shared_buffers = 2048
 (When I tried 4096 I´ve got a connection error. Don´t know what this
  means, but anyway increasing of this value did not changed anything.)

sort_mem = 2048
 (After increasing this value (from default 512) to 1024 I got an
  increase in speed from 20s to 18s - not much but better than nothing.
  Further increase to 2048 did not change anything further so I stopped
  here.)

Any other values which might help here?
