Description
I'm not sure how to describe a repro for this; I've created a warped VRT using gdalwarp and attempted to retrieve masked values with rasterio (src.read(out_shape=(3, 512, 512), masked=True)). With CPL_CURL_VERBOSE=YES, I've noticed that it makes many HTTP requests (more than 2x what an unmasked read makes), enough to make me think that it's not loading overviews.

Can you reproduce with "gdal_translate -b 1 [...] -b mask your.vrt out.tif" ?
