The Jaguar version appears to poll the source-data object every few seconds.

Well, I don't know about that, but ...

The end result is a lot more CPU use in Jaguar than in Panther.

... there is still a difference. The AppKit Release Notes say:

"NSTableView now caches the results from numberOfRowsInTableView: when possible. In the past, NSTableView messaged the data source for this value an inordinate amount of times."

Is there something I should be aware of when using NSTableView on Jaguar, to get the performance up and the behavior correct?

Cache the value for numberOfRowsInTableView: in your data source?

bye. Andreas.
