Hi,

We have a geoserver (2.0.0) running and we have published 100 tiles of a 
map (25MB GeoTiff each) as individual layers to it.

Now we issue a GetMap request for some area as shown below.

In the particular case, none of the tiles actually overlaps the 
requested area, so the resulting PNG is completely transparent (as 
expected).

Our problem now is that this request takes about a minute (6 core system 
with plenty of RAM, Win7x64, Java6x64, JBoss6).

What are we doing wrong?
How can we reduce the time needed for this request?

http://localhost:8080/geoserver/wms?VERSION=1.1.1&SERVICE=WMS
&REQUEST=GetMap
&SRS=EPSG:4326
&WIDTH=256&HEIGHT=256
&LAYERS=DEM_1,DEM_2,[...],DEM_100
&STYLES=DEM_STYLE,[...],DEM_STYLE
&FORMAT=image/png
&BGCOLOR=16777215
&TRANSPARENT=true
&BBOX=-71.103515625,42.35854391749706,-71.015625,42.42345651793833

Adding all the layers into a layer group and using that in the request 
doesn't help.

It also seems that geoserver is using a lot of memory to process this 
request.

Regards,
Stefan
