I think Instruments could do a better job of telling you what's going wrong than we could.

FWIW, the table view doesn't even know the contents of most of your 1500 rows. It asks for them from the data source as it needs them, and probably only knows the values of the currently visible cells.

Hi,

I have a NSTableView object with 3 columns and an average of 30 characters per cell.

At 1500 rows,  “ps –A -u” reports it uses 39.0% memory (there is 1GB of memory on this Mac). After the panel containing the NSTableView is closed, the app uses 1.8% (just as before opening it). The panel in question doesn’t have anything else on it …

So is this a major memory leak or a normal situation?

Thanks!
