To be quite honest it was depressing! :) The idea of loading matrices to DB worked pretty well and it was quite fast however matrix multiplication in sqlite database is ~20 times slower than doing it radiance. So even if we push them to database we have to write them back as files and use radiance `dctimestep` and `rmtxop` for multiplication. For local cases this doesn't make sense as we have the files there so why bother at all. I leave this open to discuss it later for the server side implementation.\r\n\r\ncc: @AntoineDao "}}
