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.
Roel
Hi Roel,
The performance was a known issue and we have improved it a lot in the upcoming release. We have tested it with 5000 (and above) SymbolElements and the performance is very good, panning and zooming are much smoother than before.
The performance improvement will be available first in the 2011.1 Release, which should be ready in the next 2 weeks. Please give it a try and let us know if it meets yout expectations.
Thanks,
Ivan Kotev
Hi Ivan,
Sounds promising. Eager to try out the service release! (This is a service release, right?)
Br,
Hello Roel,
I am just checking if you were able to decide on using an untested build and if this is still a possible solution for your scenario.
Looking forward to hearing from you.
I understand your predicament and usually we can provide an untested version of our internal build, however this also requires some technical time and it is already the end of the month. Could you please elaborate if such an untested version would be acceptable for your project and what is the deadline you have for switching references in your product.
Here you go.
Problem is we already release by the end of this month which is too late to onboard the latest service release for 10.3. Is there any way I could get a version with performance improvements earlier?
Is everything OK now? If yes, could you also Suggest as Answer my post?
Regards,
Alex
I have been looking through your thread and am really glad you like the improvements in the XamMap, however the 10.3 license allows only 10.3 usage, no newer nor no older version can be used with the same key. If you want to discuss your options for migrating I can suggest you reach our sales department at Sales@Infragistics.com.
Also you should be aware that the improvements in 11.1 are going to be merged in the upcoming Service Release for 10.3 to the extent to which the 10.3 functionality allows. I can suggest you wait for it to become available and test out if it would be enough for you scenario.

Please let me know if we can assist you in any other way.
