Shared buffers even on a workstation should be higher than 1000 if you
want some performance. It depends how much memory you have spare to use
for PostgreSQL. But something like
shared_buffers = 20000
maintenance_work_mem = 256000

Will certainly give you a performance boost. You will have to adjust
those figures based on whatever else you are doing on the machine.
