Description
The OpenJPEG driver is very slow with Sentinel Quicklooks like : http://sentinel-s2-l1c.s3-website.eu-central-1.amazonaws.com/tiles/31/T/EN/2017/5/26/0/preview.jp2
It seems the problem is related to the blocksize of the images (8x8) - internal tiles are processed one at a time which in this case leads to a very poor performance;
gdal_translate image.jp2 image.tif
takes about 7 seconds to execute (image size is 343x343).
