investigate Cesium tile loading latency #48

Closed michaelchin closed 2 years ago

@michaelchin, the tiles still take ages to load for me, and when I spin back to the same spot in the globe it's all blurry again. Did you figure out a way to improve this?

It seems there might not be an easy solution. Increasing tileCacheSize maybe worth a try.

viewer.scene.globe.tileCacheSize = 1000; // default 100

@nickywright I have increased the cache size. But I am not sure if it has improved the performance since my network to the geoserver is pretty fast and I can hardly see a big difference. Could you please have a quick try?

By the way, it seems the geoserver network does not like Telstra network very much. Maybe we should move the geoserver to Sydney. But the ongoing cost might be a problem. Using Amazon cloud might cost 2-3 times more.

Tried it on my laptop (using the Usyd ethernet) and my iPhone (on mobile data instead of the wifi) and it works much better now!

Much better for me too (on desktop at home).

increasing tileCacheSize works
