Wpf (too many graphics) cause awkward panning and zooming

in canvas, I have about 2000 elements based on the elements of the framework .. which include a total of 12000 drawings. This canvas is a 2-dimensional view of a complex machine. And this canvas has panning and zooming.
The drawing comes in an instant .. but when the machine / drawing is fully loaded, then panning and zooming are very inconvenient.

I could apply the bitmapcache function in .net4 to make it fast. Then the problem is when the canvas is enlarged to see the details .. pixel blocks can be seen .. which is very ugly.

Is there any way to speed this up?

I do not find a reasonable answer for this.

I tried like this: at first I had 10,000 frame elements that represent simple shapes like rectangles and circles .. It was damn slow ..

Then I tried one element of the framework that contains 10,000 graphic drawings .. yet it was slow ..

Then I tried one element of the framework that contains one visual drawing that contains 10,000 drawings .. still slow ...

I will earn a bounty, I can’t set the bitmack all the time, because the graphic is awful.
