You're not concerned with performance? I bet your users are and if they don't get reasonable performance then they can't work with "greater efficiency and ease" can they?

Eliminating server round trips is especially important in stateless environments because new connections often need to be made to the server and this is particularly expensive. If you're using .NET, an easier item to cache though would be a dataset or datatable (Preferably typed).

That said, Keith does make a good point. Caching should not be done unless you actually need to optimize performance. In this economy, throwing hardware at it is not the solution and developers and DBA's need to work together on optimizing DB operations. That is why Microsoft made SQL Server easier to manage than many other DBMS's, so they can spend more time with developers designing databases - thatis where the performance benedits come in; up front.
