<Can you confirm if your TIFF files are tiled tiff? If they aren't then the system will be slow as it converts them on the fly. I will try to convert the files to tiled TIFF with MG Rasterworkshop (MG 6.5)
<How many tiles should be shown at the 1:2000 scale? I'm guessing this should only be a small subset and hence it should be quick. max. 4 files <I think Stefan's suggestion is a good one, in particular for the ecw. <What tool are you using to convert the files? Are people using FW Tools or something else? created with ImageMagick, converted to jpg with Photoshop, to ecw with ER-Mapper <Dave Jürgen -----Original Message----- From: mapguide-users-boun...@lists.osgeo.org [mailto:mapguide-users-boun...@lists.osgeo.org] On Behalf Of Stefan Dalakov Sent: Tuesday, July 21, 2009 6:30 AM To: juergen.konr...@bluewin.ch; MapGuide Users Mail List Subject: Re: [mapguide-users] MG Error Out of memory, bad allocation Hi Jürgen One of the options may be to merge together files. I have an image, 32000x16000 tiled RGB tiff, 1.7GB in size which is served like a lightning by an old computer, not even designed to be a server, with 1.5 GB of RAM. Software configuration - same as yours. By merging rasters you can reduce the number of files almost 60 times, which means that you will have 15-20 files, roughly. Of course, you know better, if your project allows this, but in general, MGOS seems to handle easier a small number of big files, rather than a big number of small files.
