Performance issues

Hi there,

I have a problem with a very huge diagram. It's about 200 TableNodes and around 500 links, and it's almost impossible work with it, drag and drop a TableNode for move it... takes around 30 seconds.

I've got a snapshot with ANTS Profiler and in my code there is nothing spending time, the delay comes from the component. I know that it's a insane diagram Grin, I'm not going to get upset and you know we're quite happy with the component, but we'd like ask you for some advice about if we can do someting abou it.

What we can do?

Cheer.s

These are a good relief, now seems to be faster. Thanks.

Do you have any other tips about performance? How affect use gradients, shadows, background, etc.. etc...

Load and move TableNodes is still a bit heavy.

Cheers.

Shadow effects were pretty slow when they were based on the BitmapEffect class. Now with .NET3 SP1 they are based on the Effect class which is supposedly faster, but we haven't tried it. Check it anyway, disabling shadows might improve the rendering speed a bit. If there is an improvement, you might also try disabling the shadow only for the objects being moved in response to the Modifying event, and enabled it again when they are dropped.
