[mapguide-users] Performance Problem using DWF

[Martin Morrison]

Luis,

Run drawing cleanup.  Seriously, do it.   Take time to learn how each of the cleanup steps applies and use it to your best advantage.

Martin,

                The DWG file has 171700 items according to qselect command.
                The data is a set of engineering drawings (Asbuilts) that will be used as a background map where data stored in Oracle Spatial will be overlayed.

Have you run drawing cleanup?  It is on the map menu (classic workspace) -> tools -> drawing cleanup.  How much data are we really talking about?  10 points or 10 million lakes?

Martin,

                I ran the "audit" command in Map 3D and it found and fixed 584 issues.
                After that I published the file to Mapguide and the process took the same 7 hours.
                When it finished and opened the web browser to display the map, the application keeps waiting for Mapguide for a long time (more than 30 minutes) and then time out.
                The DWF file produced has about 15Mbytes and it can be opened using Design Review.
                In Map 3D I also executed the -purge command as suggested by James, but there was nothing to purge.
                Is there anything else I can try?

Regards,

luis

In Map 3D you need to make sure the dwg is in good shape before you export to either MapGuide or DWF.  Sometimes getting back to the basics are the only way to fix issues.

The way to run audit is to type "audit" on the command line in Map 3D and then decide whether or not to let it fix the errors.  Typically I run audit once without fixing just to see what I am up against and then run it a second time and let it fix the errors.  Sometimes you have to audit a couple times in a row to get the dwg clean.  If it doesn't clean up you may have bigger issues than audit can take care of and you need to resolve those.

The most important keyboard button is F1, it brings up help.  There is detailed information in help on all of the processes that I listed below.

Martin,

                I did not audited the dwg and to be honest, I don't know how to do it.
                These auditing operations should be done using Mapguide?

Something is wrong with the larger dwg.  Have you audited the dwg?  Run MapCleanup?  Purge?  Cleaned up excessive scales?

Hi,

    I'm a new Mapguide user and need some help to fix a performance problem publishing DWF data.
    Using Autodesk Map 3D I published a DWG to Mapguide. The DWG file has 10Mbytes and the processo took 7 hours. I think that it is too much time and something must be wrong but let's move on.
    After that, using Autodesk Studio, I tried to preview the layer created (DWF) and the preview windows keeps retrieving data forever and shows nothing. At the other side, Mapguide Server Processe allocate a lot of my server resources (memory and CPU) for hours and do nothing.
     I also configured the layer to accept WMS requests, but when I send a GetMap request the same problem happens. No map is returned and the server resources are increased.
     I did the same process with a smaller file (1 Mbyte) and it worked pretty fine. This small file has the same layers that the big one, but with less features.
     Have you guys some ideas?

Regards,

Luis
