40k records is nothing. I think you only need to be concerned when you actually see a performance decrease.
You are correct in that the proper indexes will certainly increase performance. I'd rather deal with one huge table, and the proper indexes, than several smaller tables and have to join them together. If you don't need online access to the data, then you can archive it.

For example, we would move all data out of certain tables that grow very large (approx. 20K - 40K records, growing by 10K / yr.) to tables that aren't used often. This theoretically would speed up queries on those often used tables. The downside of course is writing new queries that use the "archived" tables to get old data when needed. So my question is: What is the standard practice for this issue? Archive or not?
