   I wrote a tool that can walk through an ncdu binary export 4x slower than a non-parallel (cached) filesystem scan.

     @wolf480pl Partly. I get a 2x speedup by disabling line buffering on STDOUT and another 200ms by disabling the path string construction.

     Ncdu can convert the entire file to JSON in ~500ms, so there's clearly other inefficiencies left.
