Hi Simone, I am running Geoserver 2.7.2. The images are mainly old maps in jp2, here is gdalinfo of one of them:
>>> gdalinfo /storage/.../d01/00012_00010_300dpi.jp2 Driver: JP2KAK/JPEG-2000 (based on Kakadu v6.4) Files: /storage/.../d01/00012_00010_300dpi.jp2 /storage/.../d01/00012_00010_300dpi.wld Size is 2820, 16419 Coordinate System is `' Origin = (13.273995359042500,51.310171640957499) Pixel Size = (0.000343281915000,-0.000343281915000) Metadata: Corder=RPCL TIFFTAG_RESOLUTIONUNIT=3 (pixels/cm) TIFFTAG_XRESOLUTION=118.103 TIFFTAG_YRESOLUTION=118.103 Corner Coordinates: Upper Left ( 13.2739954, 51.3101716) Lower Left ( 13.2739954, 45.6738259) Upper Right ( 14.2420504, 51.3101716) Lower Right ( 14.2420504, 45.6738259) Center ( 13.7580229, 48.4919988) Band 1 Block=2048x128 Type=Byte, ColorInterp=Red Overviews: 1410x8210, 705x4105, 353x2053, 177x1027, 89x514 Image Structure Metadata: COMPRESSION=JP2000 Band 2 Block=2048x128 Type=Byte, ColorInterp=Green Overviews: 1410x8210, 705x4105, 353x2053, 177x1027, 89x514 Image Structure Metadata: COMPRESSION=JP2000 Band 3 Block=2048x128 Type=Byte, ColorInterp=Blue Overviews: 1410x8210, 705x4105, 353x2053, 177x1027, 89x514 Image Structure Metadata: COMPRESSION=JP2000 <<< Ad. -XX:MaxPermSize: Thank you, I will reconfigure this. The -Xmx is set to 2048M. Ad. layers: It is 50k (was 14k) of old maps, so I might have mistaken term "layer" for something else, the term "image" might suit it better? Anyway the Geoserver tells me, that I have 34 Workspaces, 49,721 Stores and 49,660 Layers. If I understand the system correctly, than yes, I need 50k of layers. I am using geoserver to view those maps in openLayers and via wms.
