what in fact did happen. You don't know how to make a good report? See

Tangling a file with a lot of src blocks can get quite slow because
write-region is called for each individual src block.
On my machine it takes 8 seconds to tangle a file with 160 blocks of the
same language. Tangling the file over tramp would probably take about 5
minutes.
Perhaps it would be more optimal to only save each file at the end
of src block extraction.
