The sparse_dd tool here

  • uses O_DIRECT to avoid polluting caches
  • out-of-heap buffers via Cstruct.t so we don't pollute the major heap or perform unnecessary GC
  • avoids making extra data copies
  • allows SSL to be hard-wired on or off via the config file (ie without recompile)
  • avoids piping through client stunnel when SSL is on
  • has experimental bypass-tapdisk-for-{read,write} options in the config file
