Silverlight Firestarter 2010 Session 6 - Tune Your Application: Profiling and Performance Tips

The Discussion

• 

  Great presentation!  I found the information to be quite useful/practical.  Thank you! :0)

• 

  Material in presentation seems good, but...
  There seem to be lots of distracting, minor glitches in the audio and video (maybe encoding problems?).  Audio will seem to drop out for a split second or video will jump.  These problems are present in both the 772MB and 355MB versions of the downloadable WMV.  I haven't downloaded any of the other sessions yet, but perhaps they have these kind of issues also?  I'm getting these problems on a high-end, i7 laptop, so this can't be a hardware performance issue.

  Mp4 content doesn't stream on iPad and not possible to download either...

  @Martin: Thanks for the feedback. Please try the mp4 again. i was just able to download it and play it.

  I've been trying to get profiling to work on a Silverlight project for over a year (off and on). It has never worked and I've followed some pretty obscure and rediculous instructions trying all kinds of things in the past. I thought this video was finally a simple solution to getting some profiling info on my app. Of course, it turns out not to work. I'm not sure what I have set differently because it isn't shown in the video. I get no info on my app so I downloaded the sample code and placed it in the same directory as is demoed by Mike Cook. I typed everything EXACTLY as Mike typed it except I used "Program Files (x86)" because if I used the 64bit version of IE the profiler says profiling of 64bit apps is not supported. When Mike opens the vsp it shows 669 samples at 34:12 in the video. When I open it it shows 0 samples and says "No Call Tree Data Is Available". If I click "show All Code" it says there are 9 total samples but the only items that show up are things like ntdll.dll. Can someone at Microsoft please show a real example of getting performance info on a Silverlight app and ALL the steps necessary to get this: like starting windbg and running some obscure commands to load whatever is required, etc.?

  @Jeff: Hi Jeff, one thing I mistakenly failed to mention during my demo was that I had a registry key set to force Internet Explorer to run in a single process (instead of spawning new processes for new tabs).  The key is explained on the IE blog here, by setting the 'TabProcGrowth' key to 0 you can force IE to run in a single process.  Without this key set you can't garuntuee that you're actually profiling the process the Silverlight is running within.  Please give this a try while, as you mentioned, profiling Silverlight inside of 32-bit IE.  If you have more trouble, post a new thread on the Silverlight Performance Forum and we can discuss.  Sorry that you're having issues!
