Graph.OnEnable() cost too much CPU time ! How to optimize this problem?

Hello there,

It all depends on what you are doing on the Graph OnEnable node output. The node itself does not have any performance impact, but what you have connected on its output can have. Can you please post a screenshot of your graph nodes connected to your OnEnable node output?

Thank you.

Each gameObject is initialized, it will call StartGraph function, this function will access each flowcanvas node, if the number of node is large, then consume too much main CPU time!

The CPU time cost here!
