There are also a bunch of techniques from the non-spatial world, such as data pre-summarizing, partitioning and denormalizing that can be used to turbo charge your systems through slightly altering your data model and query assumptions. Even extremely large databases can be made high performance, if you are able to constrain your assumptions about the potential variability of query parameters, just a little.
