Grafana flowcharting zooming not smoothly when draw.io diagram has many objects

[hao-prog]

Hi,
I'm using grafana-v10.2.3 and draw.io to show my diagram.
It seems like the diagram which has many objects can affect the perfomance of the zooming action.
Please let me know if there are any solution for this.
I've attached my approximate draw.io file
Thanks.
