Ciao Tom, thanks for sharing these numbers. One of the things we focused on with JAI-Ext was performance hence I am surprised but not too much (well, yeah, your mileage may vary depending on the data. Our tests where showing a closer race between new and old code). We now have to improve how things are tied up in GT/GS especially when nodata is around..
