The postgresql.conf seems fine - at least I haven't noticed anything
obviously wrong there. But we know almost nothing about your HW (not
even what kind of CPU / how many cores, etc.) or how you're using it.

For example you haven't even posted a complete top output, so we have no
idea what else is running on the box. OTOH the box seems to be rather
idle - there's plenty of CPU, RAM and the disks are rather idle.

Why exactly do you think it's the database that's slow?

We can't really help you unless you show us what exactly you consider
slow. The best thing you can probably do is to show us a slow query
along with it's EXPLAIN ANALYZE output (use explain.depesz.com to post it).

And it'd be nice to know the history around this - was it fast before,
did it get slow suddenly or over a longer period of time?
