Hi,
The following methods issue the same request to my geoserver instance
(2.0.2).
They request imagery in geotiff32 format which is a custom format I have
"invented" to carry coverage data over wms. There is a custom bean on
geoserver which I have base on worldwind map producer samples(written by the
talented what_nick).
However the problem is while the first method completes in 2-4 seconds the
second completes 20+ seconds at best.
In my debugging the streaming part in second method seems to be the problem
rather than any Imagery related performance issue.
Any suggestions,
Regards
baris
ps. maybe i should use the geotools list?
BBOX are XXX ed on purpose.
