If you want to keep your sorting to the client, you have to accept that the
time will be spent to do it. The question is *when* it will occur. A nice
option you have, if memory footprint isn't a huge concern (which with
today's computers really shouldn't be), is to use the SmartTableModel
contrib. With it, you provide the set of "views" ahead of time. In your
case, the views are different sorts. The model maintains sorted references
to the data in each of the views as data is added, so switching views is
immediate. The sorting time will be incurred once after loading your initial
large data set (and as rows are added, but small numbers of rows are
inserted into the various view reference arrays very quickly) instead of
each time the sort order is changed.
