Most Accurate Way to Get Memory Usage for Silverlight Browser Application

Question

Currently i'm tracking down a memory leak issue in a Silverlight 4 application. I can watch the memory used by iexplorer.exe increase gradually using Task Manager.

However, I am looking for a way within the Silverlight code to tell how much memory the application is currently using within the IE Process. I have tried GC.GetTotalMemory but it does not represent the actual memory usage by iexplorer.

I have developer tools for tracking down the memory leak itself, so i'm not looking for that but a method within my Silverlight code to get total IE memory usage, or at least a closer representation of what is actually being used by Silverlight instead of what the Garbage collector thinks is being used.

Answer 1

GC allocated memory is good estimation of dynamic portion of memory used by SL application. Otherwise it is unclear what other types of memory usage you need.

If you need some other data consider using VaDump first ( http://msdn.microsoft.com/en-us/magazine/dd882521.aspx linked from Using VADump to track memory usage - OpenProcess Failed c0000034). When you figure out what portion/type of memory you are interested in it should be relatively easy to get this information (you may need to collect it with native calls, but likely all can be PInvoke'ed).

Update: I think all information you looking for is avaialble through performance counters - usage sample - http://msdn.microsoft.com/en-us/library/system.diagnostics.performancecounter.countername.aspx (but I'm don't think you can get it from SL).

Answer 2

Try the visual studio profiler

"For .NET memory profiling, use “VSPerfClrEnv /samplegc” or “VSPerfClrEnv /samplegclife” in your step 1 to get either allocation profiling or allocation and lifetime profiling. "
