Hi, You say that your raster layer is slower than vector layers, but do you feel it is too slow? Your image should be served pretty fast by Mapserver. The key is that tiff file is tiled (for zoom-in situation) and that it has overviews (for zoom-out case). Could you send the gdalinfo report about your image if you suffer from slowness?
