[mapserver-users] bad jpeg2000 performance

[Holger Porath]

All,

we are trying to read jpeg2000 tiles with mapserver. We downloaded  
jasper-1.900.1.uuid and recompiled gdal 1.6.1 with it. Afterwards we  
compiled mapserver 5.0 again. We are now able to read jpeg2000 images  
with mapserver but it is extremly slow.  A getmap request for a small  
image takes more than 20 seconds. Attached you'll find the debug  
messages from mapserver. From our perspective, the resampling is  
causing the poor performance. We are wondering, why mapserver wants to  
resample the tiles. The jpeg2000 tiles all have epsg:25832 and we are  
requesting the map in epsg:25832. So do you have any ideas?

Cheers
Holger Porath
