Yeah...but again, it's not much of a choice...the rows are grouped in
"like" matches. For example, if 5 people have similar results, then the
user groups them together in a common group and will want to be able to
see these groups as a subset of the whole dataset.

One of your problems might be that you're using a grouping grid. I
tested an ADG with 5,000 rows, and the grouping version took a huge
amount of time to render, while the non-grouping version took just
four seconds.
