Remember that LL is still shipping a downright ancient KDU 4.* based

I'm pretty sure Robin's test harness is very minimal, if you are
thinking that there's a bloated clie
In theory, KDU 6.4 is supposed to be platform neutral - or at least that's one

Is it possible for you to release your test harness for these comparisons,
including the texture set?
I noticed there isn't data for linux or mac platforms, which I am curious
about. My eyeball tells me KDU is more optimized for windows than other
platforms, but I'd like to test this empirically,
Doing this out of a local cache would make it clearer what the time
for the library is. I suspect these numbers understate the kdu
advantage.
