Hello Steve, I tried the "compressed" Coord class. As expected, it requires only 16 Bytes for each instance of Coord instead of 24 bytes, but the performance improvement is small, because the frequently called method getLongitude() is now more complex, so we save a few cycles in GC and add some in at other places. If you want to try, here is the patch:
