Hi,
I have an issue regards performance when adding lots of diagram items, if I have 40,000 lines it takes around 28 seconds to add another 1000 lines, and the time gets longer and longer (30 seconds when going from 44,000 to 45,000).
I have tried using diagram BeginUpdates and EndUpdates but this doesn't seem to have much effect. I also happen to have a diagram navigator control linked to the diagram and this also gets updated even after BeginUpdates is called.
A single CPU core is also being maxxed out whilst doing this.
Is there any workaround I can do to make this quicker ?
By the way I'm running on a Win 10 PC with I7.
Regards
Toby
