Asked On July 16, 2009 09:17 AM UTC

I have attached the code to draw the nodecollection of about 5000 rectangles.

It is taking about 9 secs.
I need to cut down the performance time by ~2 sec.

Please suggest the necessary steps to be implemented to reduce the performance time.

Thanks in advance,
Krishna

Have you tried to set Rendering Style ?
By default it is set to "HighQuality"
but you can set it to "HighSpeed"

this.diagram1.Model.RenderingStyle.SmoothingMode = SmoothingMode.HighSpeed;

I've tried to change rendering style.
Perfomance is a bit better, but still extremely slow.
Any other ways to improve speed?
