Jpeg compressed images rendering slows down significantly if no overviews are available
---------------------------------------------------------------------------------------
Key: GEOS-1751
URL: http://jira.codehaus.org/browse/GEOS-1751
Project: GeoServer
Issue Type: Improvement
Components: WMS
Affects Versions: 1.6.0
Reporter: Andrea Aime
Assignee: Simone Giannecchini
Fix For: 1.6.1
The probable cause is that subsampling is performed in an inefficient way inside the readers. The slowdown factor is equal to 4 compared to a non compressed image.
The fix should include jpegs, tiff wtih jpeg compression, as well as pure png and pure gif (so, gt2 modules, worldimage and geotiff)
