Too much unmanaged memory

[venureddy]

Hi,

My screen has Telerik controls like barchart+piechart+outlookbar+2 telerikgrids+dockpane.The screen works like below
1)on first load the data gets populated in first grid and all the charts get rendered.
2)when user clicks on a tab the second grid gets populated.

I have some stats from process explorer.

		Silverlight App with Telerik Controls
Upon Frist Grid Load
Memory Usage		110 MB
VM usage		120 MB
CPU Usage		45-50% for 15-20 seconds
Upon Second Grid Load
Memory Usage		226 MB
VM usage		235 MB
CPU Usage		50-55% for 20-25 seconds

Also attached the screenshot generated from ANTS profiler.My problem is that ,if you look at the screenshot it shows too much unmanaged memory in use.Iam not sure which part of my screen or which control is causing this issue.

Could you please help me figure out whether there are any memory leaks w.r.t unmanaged memory.Even the Heap size is bit too much,because there isnt much data on the screen.

thanks
venu

Hi Venureddy,

 We have encountered similar issue. Our investigation has shown that this issue is SL4 internal memory leak, which is caused by adding large number of elements in the visual tree. Unfortunately, we were unable find way to workaround this. Our tests indicated that issue is resolved in SL5.

What we can suggest as the only option is to add custom styles/templates that reduces the visual elements used and remove the unused ones.

How do your tests show this is resolved in SL5 when your controls don't work in SL5 RC?

Hello Glen,

Some of the controls were working just fine with SIlverlight 5 RC and we are also getting private builds from Microsoft with the latest builds of SL5 so all the problems with RC are now gone as Microsoft have fixed the issues we reported them that were breaking the backward compatibility.

Kind regards,
