We are creating a WebPpp for Tablets.

Because our WebApp needs to have offline capabilities, we are saving an entire VectorTile layer in a pouchDB (around 25k tiles).

This layer is used for orientation (much like google maps),
it includes streets, buildings, forests and so on.

The Tiles are generated with the GeoServer 2.11.1 Extension.

Now our problem is, chrome crashed ('Oh no' message) when we move the map around or zoom in/out. Firefox doesn't work better, doesn't crash but slow as hell.
For testing purposes I deactivated any styling (just basic) and just this layer is displayed.

Does anyone know why the browser crashes, or is there a way to find out? Also are there alternatives?

Tablet that is used to test: Galaxy note pro, is this tablet just bad for graphical apps?
Other tablets did work fine.

thanks

メモリが不足している可能性があります。デフォルト (128) の代わりに、たとえば 32 などol.source.VectorTileの小さい値で構成します。cacheSize

new ol.source.VectorTile({
  cacheSize: 32,
  // ...
});
