Hmph, perhaps none of these is truly expensive if that is the case? I am not talking about ~10 or ~30 seconds in absolute terms, but reacting to "excluding the ones only halves the time." The files used in the test vector seem to be all small. Is the expensiveness due to the fact that there are so many of them, and not due to some specific conversion being very slow?
