Hello again -
One last issue and I think I'm all set. I noticed that CPU usage spikes while a document is being displayed. Once the document loads, Windows task manager reports up to 50% CPU usage on a laptop i5 processor and it doesn't let up until I close the application.
On IE this doesn't seem to impair usage of the app, but on Firefox it becomes very laggy.
If I set the visibility of the control to Collapsed then the CPU usage drops off entirely, so it seems to be specifically while a document is being rendered. Changing the scaling of the document does not appear to have any impact. I'm wondering if you have
any thoughts on why the CPU usage is so constant? Some notes:
- Firefox 10
- IE 8
- Silverlight 4
- It's a one-page XPS that was generated from an Excel document
- I pre-download the document in its entirety and then feed the stream to a default package reader
I'm wondering if you've observed symptoms of this issue before and have any ideas on where I can start looking. Thanks!
