Very slow rendering of a small GRIB file #18

I am struggling to render this file. I think it is a problem with NODATA value.

Dataset has around 1 milion of cells.

I think the problem may simply be with the data flow in MDAL->QGIS (related to https://github.com/lutraconsulting/MDAL/issues/13), since now all the data is duplicated in the memory and we do not filter it by extent.

definitely slower than in Crayfish and worth of investigation.

closing, this is QGIS issue
