Hi list, I have a very big problems on tiles generatig by MgCooker. I've made many tests in the last months with several projects and different machines, and the conclusion is that is nearly impossible to use, or you can use if you can wait days or weeks for finishing processes. In my case , I know nobody that can wait for so much on updating his data.
I would like to share my experience with somebody that really uses MgCooker for tiles generation, just to understand if it is really possible to use it and at which conditions. Today I've opened a case ( http://trac.osgeo.org/mapguide/ticket/1999 ticket 1999 ) becasue I've discovered that more than 90% of tiles are blank and useless, so more than 90% of time is totally wasted time. I've just finished a last comparison test with several options on MgCooker vs AIMS Studio. Here you are my results. The project is very light: - a map with one base layer with 20 layers from shapfiles. - the extention area is 50 km2, a very little town. I use processor Intel Xeon X3440 @ 2.53Ghz 2.53Ghz (2 processor) on Windows Server 2008 64bits. Serverconfig.ini is configured as follows: RenderOnly = 0 TileCachePath =C:\Program Files\OSGeo\MapGuide\Server\Repositories\TileCache\ TileColumnsPerFolder = 500 TileRowsPerFolder = 500 DefaultTileSizeX = 1000 DefaultTileSizeY = 1000 ImageFormat = PNG I've configured tiles for scales: - 200 - 500 - 1'000 - 2'500 - 5'000 - 35'000 MgCooker performances: - if I use standard configuration, 20 concurrent process with CPU 80%-90%: 1'012'588 tiles, 100 tiles each minute - if I use official method with 1 meter pr. unit, 20 concurrent process with CPU 80%-90%: 460'458 tiles, 100 tiles each minute With MgCooker nothing changes if I redefine a closer bounding box AIMS Studio 2012 - if I don't redefine a bounding box and with 10 concurrent process (the max in AIMS Studio) I get 138'667 tiles to be generated - if I redefine a bounding box closer to the town and with 10 concurrent process I get 69'089 tiles to be generated Both Mapguide and AIMS generated a big amount of blank and useless tiles, but with AIMS I can reduce 460'458 tiles to 69'089 tiles. Both products waste a lot of time in generating blank tiles (about 80% blank tiles for AIMS and 90%-95% and more for MgCooker). If somebody wants to take a try to the process to check and compare time, I've attached this project to http://trac.osgeo.org/mapguide/ticket/1999 ticket 1999 . Are there anybody that has the same troubles? Any workaround? -- View this message in context: http://osgeo-org.1560.n6.nabble.com/MgCooker-bad-performance-I-can-t-use-it-Help-tp4968806.html Sent from the MapGuide Users mailing list archive at Nabble.com. _______________________________________________ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users
