TreeUtil sometimes stops being responsive during debugging #29

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Sometimes during debugging, TreeUtil stops being responsive. For example, if we 
place a breakpoint on the "while" of belief iterations, we can use TreeUtil 
when the program pauses on the first iteration, but not at the pause of the 
second iteration. Can we fix that?

Hi Rodrigo,

This is similar to what I just commented in Issue 30, more than likely what you 
are seeing here is maximum heap space being reached, which will cause a big 
reduction in performance, without necessarily falling over immediately. The 
recommended approach is to use:

-Xmx8g

at a minimum if you are trying to inspect large traces using the find 
functionality. Let me know your thoughts as regards this.

Hi Ciaran,

I see. Perhaps I confused slowness with freezing. I see now that sometimes it 
takes quite a long time (almost 10 secs) just to select a node.

For the record, I added the -Xmx8g flag but it did not seem to make a 
difference.
