Frank, I've left those RRD and I suspect that for some reason the pyramids are not read... In fact the performance is very good for zoomed in views (street level)... but it is very slow for zoom out views (city level)... and I can see the IO working very hard...
is there any way to see if MapServer/gdal is reading the pyramids correctly ? thanks On Tue, Oct 19, 2010 at 2:08 PM, Frank Warmerdam <[email protected]>wrote: > Sebastian E.
