when working on fully functional hard drives, under linux it performs full
i/o speed. when compiled under osx with the default compile flags, it is
magnitude times slower, sometimes crawling to Kb/s. the problem persists if
the output file is /dev/null.
I have tried it on 10.5, 10.6, 10.7 and 10.8. the same issue.

Try using /dev/rdiskX as source instead of /dev/diskX. Does that speed things up?
Greetings,
