I would start by trying to optimize the tables/indexes/queries before before taking any of the measures you listed. Have you dug into the poorly performing queries to the point where you are absolutely convinced you have reached the limit of your RDBMS's capabilities?

Edit: if you are indeed properly optimized, but still have problems, consider creating a Materialized View for the exact data you need. That may or may not be a good idea based on more factors than you have provided, but I would put it at the top of the list of things to consider.
