Fastest way to serve rasters for visualisation purposes only without using a tile-cache.

I have raster datasets in GeoTIFF format which have to be served with ArcGIS Server 10.5.1 for visual purposes only. No image processing is needed but it does need to be rendered fast. Which method provides the fastest raster service with ArcGIS Server 10.5.1? I have 32 GB ram and a 4 Core Windows 10 machine.

Here are the details;

  • Format = 1 Bit GeoTIF
  • Compression = deflate
  • CRS = Same as map client and therefore doesn't need to be reprojected.

My choices are:

Imageserver Service:

  • Import as raster dataset into SDE with Overviews in SDE also.
  • Create SDE Mosaic-dataset referencing SDE Raster with overviews (in sde or external)
  • Create SDE Moaic-dataset referencing File based GeoTIFF with external overviews
  • Import raster dataset into FGDB with overviews.
  • leave raster as GeoTIFF on Filesystem and publish as ImageService

Map Servcice: Add GeoTIFF to mxd and serve as MapService Add FGDB Raster dataset to mxd and create MapService

Which method would serve tiles the quickest?
