[MapProxy] How to check if the defined cache is being used

[Rahkonen Jukka (MML)]

Hi,

If you use MapCache as WMS server https://mapserver.org/mapcache/services.html#ogc-wms-service then it takes from the cache all the tiles which are needed to fill the area defined by WIDTH and HEIGHT in GetMap, combines them, and crops to the exact area that was requested. The documentation about this is short https://mapserver.org/mapcache/tile_assembling.html#mapcache-tile-assembling.

If the layer in the original WMS is fast to render then the MapCache WMS can well be slower. The advantage of tile cache is most obvious with clients that request the tiles directly. However, even WMS may be accelerated if the map is very heavy to render.

How can I check if the defined cache is being used? The MapProxy WMS runs slower than the original WMS, although a cache including seeding is defined.
The cache was successfully built up by seeding.

I would be happy about a hint.

Regards Stefan
