That is a pretty generic question.  Have you run into problems?  what
have you tried?

In general, use COPY.  If its a one time load, temporarily disable fsync.

I use shp2pgsql all the time, and it loads 10's of thousands of records
a second.  (I've never timed it, it was never something slow that I
needed to fix.  I just ran it and went on).

Do you have shape files you need to load?  Have you tuned your
postgresql.conf?  Do you want a util to import data for you, or are you
writing your own? Are you using PostGIS?

No one can give you specifics without a bunch more detail about what you
want.
