In my experience it is faster to render a single tile rather than each of the layers individually. This can be done by grouping on GS, or submitting a WMS request that asks for groupings of layers. My guess is this matches other’s experiences… .
If you are using a web client, this is particularly true, as many are configured to grab only 4 tiles (requests) at a time regardless of how many the network can handle. This deficiency can be worked around by having multiple DNS entries for the same server, but then you may need to play some proxy games if you want to use those same server names to server GetFeatureInfo, WFS and other XML shipping approaches. http://www.clemetparks.com/images/esig/cmp-ms-90x122.pngStephen Mather Geographic Information Systems (GIS) Manager (216) 635-3243 [email protected] <http://www.clemetparks.com/> clevelandmetroparks.com From: Robert Buckley [mailto:[email protected]] Sent: Tuesday, January 24, 2012 11:25 AM To: [email protected] Subject: [Geoserver-users] Speed advantage when serving grouped layers? Hi, Is there a performance advantage to loading grouped layers into a mashup rather than loading individual layers? Common sense says yes due to the fact that the server only has to serve one tile instead of 'n' tiles..but does it take longer to render the 1 tile in geoserver? Yours, Rob
