JPEG2000 performance numbers on cornerstone

At yesterday's OHIF Community meeting I reported a 3x speedup in JPEG2000 performance with the latest dev branch of cornerstone and that we are now within 50% of native performance.  The speedup really surprised me and I can't really explain it other than there must have been many speed improvements in OpenJPEG 2.1.1.  After this presentation OpenJPEG 2.1.2 was released which has additional speed improvements and additional ones are currently in development.  The future for JPEG2000 performance is looking very good.
