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
of the claims the mfr. is making about the new version.

I can't give out the texture set, hopefully as per a previous

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.

Hi everyone
I have been doing some direct comparison between KDU and Openjpeg and
have some metrics to share with the rest of you (in case you have not
seen them already flying around on #opensl/ or AWG chat)
