xammap navigation performance

Roel posted over 13 years ago

Hi,

I have latest version of XamMap (latest service release) and if I add 100 SymbolElements, and a shape file of 50kb with ~50 shapes, navigation (e.g. zooming in and out) gets already quite slow. I feel that the number of SymbolElements is affecting the performance quite drastically.(more than the size of the shapefile does)

If I add 1000 SymbolElements (small .png file), Navigation becomes virtually impossible. On Bing Maps Silverlight control, I was previously able to add 5000 elements and navigate still quite smoothly.

The threshold of a smooth navigation is too low. I already add all the SymbolElements in one go to the ElementCollection, and 100 data points is not a whole lot.

This low performance is a show stopper for us using Infragistics XamMap (or stopper for buying additional licenses). Is there any way Infragistics could look at improving the performance?

Thanks for letting me know.

Hi Roel,

I am glad to hear that the installation succeeded.

Regarding your last question, you can't use the license key from 10.3 for the 11.1 version. However, the performance improvements in xamMap are going to be included in our next 10.3 Service Release, which is expected at the beginning of July. An option to get it earlier is to request an untested build by contacting our Developer Support team.

Best Regards,

Hi,

After uninstalling version 10.3 it worked. Also this time I clicked NetAdvantage_SilverlightDV_20111.msi, maybe last time I did the NetAdvantage_Ultimate_20111.exe

I tried the sample app, and there are indeed some great performance improvements. Good work!

Another question: we just bought a 10.3 license, can we use this key for the 11.1 version also?

Br,

Roel

In general the error I see in the log there may appear because:

The location of the installer is on an encrypted directory. Place the installer in a non-encrypted directory and re-run the installer.

There is a corrupted version of Windows Installer engine on the machine. Re-install the Windows Installer Engine.

The installation does not have access to the Application Data directory or there is not enough space to run the setup.

The installation is being run over a Terminal Server or mapped network drive. Run the installer from a local location.

Thanks,

Alex

Hi Roel,

I will try to reproduce the issue. Could you provide us with all the logs from the "Log Files" folder that is located next to the Platform installer .exe ?

It is best to open a support case for that and provide all the details to Developer Support.

Regards,

Alex
