Yes... you probably loaded the entire list into the table, there is no
need for doing that, there is a generic datamodel interface/class
underneath of all things, by implementing your own datamodel
you can achieve pagination and only have to load one page per time.
That way I managed tables of 15.000 rows and more without any
significant performance impact.
But beware, implementing a datamodel is not what I would call a walk in
the park.
