how many czml entities browser can take bear ?

now I am adding DataSource, czml file and geojson file.
adding czml file can make a better performance, but almost 6-10 entities will make browser lower and lower, but FPS is not that high, and I have a good graphic card.

adding geojson file will run smoothly, but performance is not good as czml.

yeah, I like czml file adding and better performance, is there any optimization method I can use.

Thx , BTW , ignore my poor English :slight_smile:
