More RAM, and faster hard drives top the list. A good CPU is nice, but
bump RAM and hard drives first.

(Which would make more difference depends on your situation.)

I'll let someone else answer this, but it is fairly simple in theory.
Depending on your setup, it may only be a single configuration setting.

Of course, that means it depends a lot on what processes are doing the
communication, and how they are configured.

There are various ways to do this. You could do a regular pg_dump on a
cron schedule. You could use triggers with pgsql to automatically update
a concurrent database. You could build a distributed database, in a
master/slave configuration. Your best choice depends on your needs.

Sorry, don't know a thing about IIS.
