ColdFusion programmers have a construct built into the RecordSet class on the client and server that can reduce the time it takes for the data to display. Chapter 5 went into detail about the technique of RecordSet paging. In many cases, this technique improves the apparent performance of your application; your users will see results on the screen even before the download of the entire recordset is complete. Improving the apparent performance of your application can often have as much of an impact on the end user as improving the actual performance of the application. Your user can judge the application only by what he sees.
