Dejan,
What I expressed rather poorly was that on consideration is what is
a typical usage scenario for your user. If the nature of your mapping
application is that folks start looking at the whole map, and then
zoom in to a local area, then you will want to ensure that rendering
the whole dataset for an overview view is fast, because this is a common
case.
If the nature of your application is that people are generally only looking
at a small area, then you might not be too concerned about whether
overview views of the whole map are somewhat slow.
Best regards,
