Aaron,
did you bench timings using GDAL API & utilities (typically with
gdal_translate) ? The ones indicated in the PR use the utilities that
come which each library, but the integration within a GDAL driver might
have some influence on the timings.
What about single threaded usage ?

Hi Folks,
I would like to draw people's attention once again to the pending JPEG
2000 driver PR
https://github.com/OSGeo/gdal/pull/3449
<https://github.com/OSGeo/gdal/pull/3449>
which was opened 3 months ago. Since I last posted, the driver now
has an autotest script courtesy of Frank Warmerdam, and all tests are
passing.
In a nutshell, performance is 2-5 times faster than the only other
viable open source driver, from OpenJPEG, in several common geospatial
work flows. And performance rises by around 2X if the new HTJ2K
entropy coder is used. The AGPL license will not work for everyone,
which is why the driver is disabled by default.
We've already discussed this at length in the previous thread and in
the PR, but if you would like to see this new driver merged, please
head over to the PR and give it a thumbs up. Or, if you don't want
this driver merged, please share your feedback on the PR.
Kind Regards,
Aaron
