I have about 300 vector and 30 raster layers in a GeoServer instance (version 2.7.4) and when the client makes a WMS GetCapabilites request, it takes about 3 minutes to receive the response. The vector layers are stored in a PostGIS database while raster layers are stored as GeoTIFF files.
In the field: Limited SRS list of WMS admin page, I have imported the SRSs that I'm using like:
4326, 3857, 2100
and the result of list in WMS GetCapabilities file is:
<!--Limited list of EPSG projections:--> <SRS>EPSG:4326</SRS> <SRS>EPSG:3857</SRS> <SRS>EPSG:2100</SRS>
Nevertheless, the request takes too long to response. I found a similar question: Limited CRS options of GeoServer WMS
In the answer, @lubojr says the following: "I just missed the small drop-down list with workspace selection on top of the WMS settings page"
I also selected the corresponding workspace in that dropdown menu but the result was the same.
Any suggestions ?
