if you take a model and click on an elements I see that the GC is kicked in
each time I change a list element.
There is something strange. We saw that with cyrille.

How do you know about the GC? Using MessageTally?

Hi Stef,
Could you describe the scenario in more details?

I see it!
The icon gets changed really fast and you feel it.
Doru the scenario is simple, I opened a large model and clicked on an item of the list
then with the keyboard I wanted to move
down and I see all the time the gc kicked in. It measn that a lot of garbage is
generated.

Oh, I see. You were scrolling between multiple list of tens of
thousands of entities that were displayed on the next pane. The GC
most probably comes from the MorphTreeMorph which has to create models
to display all these elements.
I am not sure what can be done about that.

may be we can ask alain if we can get a caching tree.

A caching system would work if you go twice over the same item. But,
in this case you just go through multiple lists. What would you cache?
For each line in the list, you get multiple morphs. That is quite
expensive. There already is the paging mechanism to only show a
limited amount of items, and this is now workable. But, it still isn't
quite as it should be.
The coolest thing would be a parallel computation of the morphs :)

I meant only computing what is shown.

This is already provided with the paging mechanism, and with another
one that does lazy computation of what is displayed (however, this
does not scale well).
Is there a way to profile a GC problem?
