I have checked. Yes, in using S2 COG with images in tiff format gdal makes
5 requests for getting 100x100px images and speed significantly higher in
comparison with jp2. Unfortunately the size of tiff-file in this case is
twice higher than corresponding jp2.

You can check how a S2 COG compares at
https://registry.opendata.aws/sentinel-2-l2a-cogs/
You should hopefully see a lot less network requests when accessing a sub
block directly.

'S2A_MSIL1C_20201024T104121_
