Something in caching mechanism is going wrong and resulting in the file TiffTags being read for every tile. Attached is a CPU sample of a RasterFrames job that highlights the problem. This is also evident in overall runtime of the job as compared to using GDAL RasterSource.

Can it cache it with the lazy val inside being not evaluated and never updated later?
