Review on notebook 8, usecase reprojection #5

Description

@guillaumeeb

While it is really nice to build such a notebook for performance and resource usage comparison, beware of comparing the same things:

  • With rasterio, the reprojection is done band by band, which may explain the difference in memory consumption.
  • Maybe it would be nice trying to measure reprojection in memory, as IO might be the bottleneck.
  • With Dask, you also measure the client creation time which is probably not negligible in this simple case,
  • Moreover, with a Dask client/cluster, I think writing to a TIF file involve a lot of locks (chunks are written in sequence)
  • We probably don't write tiled Geotiff here.
