Too many nodes lead to Kartun

Too many nodes lead to Kartun。
How to solve it。

The Kartun phenomenon occurs when moving nodes。

I’m sorry, but I don’t understand what you mean. What is the problem and what would you like?

My interface now has more than 300 nodes.
These nodes make my program very slow.
Are there any good solutions?

Could you please be very specific about how your app is slow?
