Hello all,

I am using Geoserver 2.16.1 with Vector Tile extension.
I was able to publish a multipoint ShapeFile as a vector tile and see it in
my OpenLayers 6 application.
However, the service is very slow.
I am using the application/vnd.mapbox-vector-tile format as suggested in
https://docs.geoserver.org/stable/en/user/extensions/vectortiles/tutorial.html.
The layer contains millions of points, and as the extent I am viewing is
large the points get very long to display on the map.
Their projection is 900913 and the view of my map is 3857, so I guess this
is fine as there should be no reprojection going on slowing down the
process.
I tried to seed the cache going to speed up everything.
I went into Tile Caching -> Tile Layers -> <My_layer> and clicking the
"Seed/Truncate" link.
Then, I chose:
 - Type of operation: Seed - generate missing tiles
- grid set: EPSG:900913
- format: application/vnd.mapbox-vector-tile
- scale: 0 to 14.
and pressed submit.
After less than 5 minutes, apparently the process ended successfully, but
under disk usage I still se N/A.
So I guess that no cache has been seeded, right?
What am I doing wrong? Is it not the best choice to use vector tile for my
dataset?

Thanks in advance.

Umberto
