I found this some days ago WP7 best practices - Performance

Its mostly commented links to articles (some of them mentioned before) and sources (like Jeff Wilcox Performance Progress Bar).

And remember: Listboxes are like kryptonite to WP7 performance =)

The #1 performance enhancer I've found for my apps, especially for animations that use the UI thread, is to manually set BitmapCache for all UIElements. This significantly improves all animation.

General

  • If your app loads very fast get rid
    off the spash screen.
  • Code generation in the compact framework is not the same as Windows’ code. Jitter is optimized to run fast, not to produce the fastest code.
  • Property is just a function for .Net CF.

Silverlight

  • Take as much as you can from Compositor Thread (for callback animations use BitmapCache).
  • Use Canvas or custom popup instead of default one (Popup class) – lack of hardware acceleration.

XNA

  • Use DXT format for textures and pack them into 1 file (faster loading and fewer GPU texture switches).
  • For things like game stats avoid using strings( immutable). SpriteBatch.DrawString can take a StringBuilder directly for drawing text.
  • Avoid using/abusing LINQ and foreach (it may causes garbage). Use Jagged arrays( arrays of arrays) instead of 2d arrays.
