Hello, One of my project would greatly benefit from a much faster rendering. After some testing, the bulk (>99%) of the time is spent at rendering the layer with QgsRasterLayer(...,...). What I have also noticed is that rendering time does not change with the number of cores, which suggests that the renderer might be using a single thread. I checked the API documentation but couldn't find anything about multithreading or some other procedure to accelerate rendering. I was wondering if anyone has any suggestion or has faced a similar difficulty. Thanks. (Note: The data provider is 'gdal' and I'm using QGIS-3.30)
