<p>Aaron,</p>
<p>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.</p>
<p>What about single threaded usage ?</p>
<p>Even<br>

<div dir="ltr">Hi Folks,
<div><br>
</div>
<div>I would like to draw people's attention once again to the
pending JPEG 2000 driver PR</div>
<div>
<div><a href="https://github.com/OSGeo/gdal/pull/3449"
moz-do-not-send="true">https://github.com/OSGeo/gdal/pull/3449</a><br>
</div>
</div>
<div>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. </div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>Kind Regards,</div>
