[news.eclipse.tools.gef] 6000 nodes, 34 seconds to load diagram.

[Steve Jones <steve@xxxxxxxxxxxxxxxxxx>]

Hi,

I'm using ScrollingGraphicalViewer to display a diagram of 6000+ nodes.

I use XYLayout, each node is positioned as if in a list with a row 
height of about 50 pixels.

My problem is that the diagram is taking ages to load. Using log4j the 
breakdown of the time needed to display 6000 nodes is:

Load model from file    1s
Create all edit parts   5s
**Unexplained delay**   10s
Draw2d layout           18s

Total delay             34s

I cannot explain the 10 second delay I get between the last edit part 
being created and the first IFigure#layout call.

The figure associated with each edit part uses several nested panels 
each with it's own toolbar layout. Is this why the layout is taking so long?

I'd like to get the load down to between 5 and 10 seconds is this 
possible or am I dreaming?

Any suggestions would be most welcome.

Thanks, Steve.
