For faster visualization, pyramids can be generated by using force-pyramid for any cubed data, inclusively GDAL virtual format-files. Pyramid layers are copies of the original data at reduced resolution. This significantly increases loading and response times for visualization. However, keep in mind that pyramids consume some disc space.
