My node-red-dashboard so slow

Hi all! My node-red-dashboard slow response when I touch the icon on the dashboard, how can i fix it?!

You could start by providing a ot more information.
are you using graphs? If so how much data are you sending to it and how frequently?
What platform are you running NR on? What version of NR?
Are you accessing NR on your local network?

Go read your post and then ask yourself, if you didn't know your flows or have access to them, how would you answer your queston.

Also what do you mean by touching the icon?
