GC called between each item list selection in Moose finder

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. Stef _______________________________________________ Moose-dev mailing list [hidden email] https://www.iam.unibe.ch/mailman/listinfo/moose-dev |

How do you know about the GC? Using MessageTally?

Hi Stef,
Could you describe the scenario in more details? Doru On 3 May 2010, at 17:26, Alexandre Bergel wrote: > How do you know about the GC?

In reply to this post by Alexandre Bergel
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. On May 3, 2010, at 5:26 PM, Alexandre Bergel wrote: > How do you know about the GC?

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.

I do not see how this would solve the problem, but maybe I am missing something. 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 :) Doru >> I am not sure what can be done about that. >> >> Doru >> >> >> On 3 May 2010, at 20:30, Stéphane Ducasse wrote: >> >>> 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.

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?
