At 1500 rows, “ps –A -u” reports it uses 39.0% memory (there is 1GB

in question doesn’t have anything else on it …
So is this a major memory leak or a normal situation?
If this is normal or not probably depends on the size of the objects
that you represent in the table view. You might only expose the "name"
property of an object in the table view, but the object itself could
of course have a ton of other properties that uses up a lot of memory.
As you get back the memory when you close the panel, it doesn't sound
like you have a memory leak per se.
Whenever you think that you use too much memory, or want to track down
some of the memory that you inevitably leak, I'd suggest that you take
a look at the performance tool Instruments, in particular the Object
Allocations and Leaks templates that should be able to answer these
questions.
