Hi Andrea, * What OS and GeoServer version are you using? We use ubuntu, and geoserver 2.8.1 * Is it a image mosaic? we have hundreds of tif files, and the largest tif file is about 800M. * Are you routinely trying to display all of the mosaic, or just parts of it? Each file will be displayed individually. * Do you have the tiffs already retiled and with overviews? We are going to visualize the maps using a Django framework: http://maps-test.qed.ai/layers/?limit=100&offset=0 Since geoserver requires all the tif files are saved locally in the server, we then need a huge server. Usually we use S3 to store data. If we do that for geoserver, the visualization in the site will be too slow? --- Jiehua Chen, Ph.D. QED | http://qed.ai On Tue, Jan 26, 2016 at 12:17 AM, Andrea Aime <and...@ge...> wrote: > On Tue, Jan 26, 2016 at 7:38 AM, Jiehua Chen <j...@qe...> wrote: > >> Hi, >> >> We are running into scalability issues with geoserver.
