>>Try this for a 1,000,000 record (same argument you used). Since it's is the norm that the tables are NOT filtered, and they *can* filter them. Also these main tables seldom reach such amount of records. (most mid-sized companies don't have 1,000,000 clients, articles, employees)

When all you want to do is poping up a maintainance form for unfiltered main tables (Articles, clients, employees) where the default is non-filtered you don't want a delay of a few seconds. The form should pop-up inmediately.

Also note that 21 seconds is a long time for inpatient users. Things might get much worse when users use somewhat outdated hardware on a heavy used network with multiple applications open.
