I'm sure Jack has better data than this, but NetInfo can be the source
of much delay, on 10.2.x, because it runs old and rather poorly
written "plugins" to gather data to resolve address info.  The
solution appears to be: make sure that your local NetInfo DB doesn't
have a "locations" key, and that you have enabled "BSD Configuration
Files", and disabled "NetInfo", using the "Directory Access" app.
This can speed up address info lookups by two orders of magnitude.
