Hi, As a vivid WMS user/debugger, I see that QGIS is firing 9 requests per 'view-extent' currently.
I'm aware of cache etc etc... but... especially when using temporal filters for example, do others agree with me that this is more or less useless? I'm also aware that a lot of WMS are actually just WMS interfaces in front of a cached WMTS, but still. - some (governmental) services nowadays are still free for fair use, but: firing 9 times the actual requests costs resources/energy/maybe money - before the WMTS I ran WMS services sometimes with pretty heavy styling, so on higher zoomlevels you do NOT want your clients to fire 9 requests, and just effectively use 1 ... So in short: should I try to add some kind of (hidden?) option to minimize the number of requests? To test a wms of all municipalities of NL: https://geodata.nationaalgeoregister.nl/bestuurlijkegrenzen/ows?SERVICE=WMS (layer 'gemeenten', EPSG:28992) And look in F12/debugging window the number of GetMap requests fired when zoomed in... I copied/created polgyons of the requests, and (see screenie) indeed looking at the center 'tile', the 8 surrounding requests are also fired.... Currently looking into this. Regards, Richard Duivenvoorde
