I wonder if the fact that the data is highly compressed (short types converted to float64 with the scaled and offset attributes) can have an influence on dask performance and memory consumption? (especially the later)

Memory consumption, yes, performance, not so much. Scale/offset (de)compression can be applied super fast, unlike zlib compression which can be 10x slower than reading from disk.
