Cesium Performance Optimization

Hi all,

We're doing a "see the world" application, where we have a website using Cesium go through and zoom on various national parks and cities throughout the world. One thing that we've noticed is that it takes 3-4 seconds to get Imagery tiles. The list of destinations is not very big and is static.

While looking at the demo app: http://cesiumjs.org/Cesium/Build/Apps/CesiumViewer/
There appears to be almost zero lag.

Using, default out-of-the-box Cesium, what are some tweaks we can make for better performance? Is there a caching mechanism for Imagery tiles that we can turn on?


Hi Chris,

CesiumViewer isn’t doing anything special with regard to imagery, so I’m not sure why you would see different performance there versus your own application. Does your application use terrain?
