One could do this already without changing mapserver, just at the web server config. It would be hard to control in mapserver when you’d want to do this.

We would want to test how effective this would be for larger mapfiles (i.e. reading mapfile vs. rendering Capabilities XML). Feel free to open an issue if this could be helpful/is of interest.

Learn why this is important Hi it took 40 s Merry Christmas On 20/12/2022 15:38, Rahkonen Jukka wrote: Hi, The time is not a constant (number of layers * x milliseconds). For example, it is faster to generate the layer BoundingBox into GetCapabilities if the wms_extent metadata is set for the layer https://www.mapserver.org/ogc/wms_server.html but how much faster it is depends on the data source. I think that instead of 1200 layers you could have just one time enabled layer https://www.mapserver.org/ogc/wms_time.html. -Jukka Rahkonen- Lähettäjä: MapServer-users <mapserver-users-boun...@lists.osgeo.org> Puolesta Marcin Niemyjski via MapServer-users Lähetetty: tiistai 20. joulukuuta 2022 16.18 Vastaanottaja: Oskar Ravhed <oskar.rav...@t-kartor.com>; mapserver-users@lists.osgeo.org Aihe: Re: [MapServer-users] Failed to download capabilities:Download of capabilities failed: Connection on mapfile with more than 1000 layers Great advice, thank you Oskar. Could you tell me how long it takes to load the WMS into qgis or GetCap with that many layers? I am also interested in what purpose you are using the WMS with this amount of data. Could you share it? In my case it is daily Sentinel-1 imagery for the whole world from the beginning of 2021.

I have 3234 layers in a service and it works fine. also works fine with 10.000 layers 1 try the getcap in browser 2a if step 1 is success change network timeout in qgis 2b if step 1 does not work change timeouts on server and check mapserver log On 20/12/2022 09:59, Jörg Thomsen (WhereGroup) wrote: > Hi, > > funny, how you type twelve. > > 1200 are very much and I guess no one has tried this before. > So to your question: I would say yes. > > I suggest to split it into several services / mapfiles.
