Hi Seth, as you suggested, I've added the Extent parameter to all of my layers, and it resulted in decreasing time to 5m33.534s. But still, it's quite a lot of time for generating 1.5 MiB file.
Any other suggestions? Maybe there is something wrong with projection so beyond just serving data mapserver have to reproject it multiple times? (more than one time by using tilesrs option)?

Hi Marcin, As a first test I'd recommend adding in EXTENTs to all your layers (and ensuring they are correct): EXTENT 1334552.857598 5342648.587634 4715044.821842 7547620.486088 If these are missing MapServer will often try and calculate these from the datasource automatically. Depending on the request type this calculation could be made multiple times.

The WMS loads quite fast, but the issue arises with the time it takes to generate a requested WCS tile: https://pasteboard.co/8G8uF41jqgHc.png It takes almost 5 minutes to generate the tile, and the received data is 1.5 MiB (which is it's actual size). Additionally, I am sending you URLs to sample data: https://s3.waw3-1.cloudferro.com/swift/v1/Julien/Data/T34UFD_20230708T093549_TCI_60m.jp2 https://s3.waw3-1.cloudferro.com/swift/v1/Julien/Data/T37TCN_20220605T083559_TCI_60m.jp2 The case is - how to speed it up? Am I making any goofy mistakes? I would be grateful for any recommendations or if you notice any errors, I might be making :) Best, Marcin _______________________________________________ MapServer-users mailing list MapServer-users@lists.osgeo.org<mailto:MapServer-users@lists.osgeo.org> https://lists.osgeo.org/mailman/listinfo/mapserver-users
