Ummm, maybe I've missed something here but I don't think a 'slow server' is an effective simulation of a dial-up connection. If your queries are getting bogged down then a faster server is going to be an effective solution. A slow dial-up just slows the rate at which the end user can receive the information but has no real effect on the speed at which the server physically generates it (ie. Back-end processing). If your query is as you describe then perhaps a more appropriate approach would be to use a scratch table in your database and, after having queried your large database, write the results back as a sub-set in a different table - then just carry a pointer variable from page to page within your site to query that scratch table - it should be a very fast query as the results will be precisely what you need and ordered ready to go.
