How to improve feature layer performance with esri javascript api 4.15

Question

I am creating a feature layer with layer url from esri online.

It currently has 250 000 data points. But with this 250k points itself it is rendering extremely slow. I also using mode on demand as

mode: FeatureLayer.MODE_ONDEMAND

How can i improve the performance with feature layer? Any reference is appreciated

You could use WebGL:

Or try to use canvas rendering instead of svg
