One test in particular that reveals a lot about how the canvas works, you may be interested in trying...
Draw a full screen image in one go and time it. Then draw the same image in three sections (to the same layer) with the appropriately different TargetRects and SourceRects, so you're essentially drawing the exact same data, from the exact same file, to the screen. I was surprised at the results.
I haven't tested yet, but are you scaling? We've found that if you can get away with smaller source images, it's much quicker.
Also, if you haven't already, take a two pixel PNG with different colors for each pixel, and scale that up. You get interpolation between the color differences. Easy, super small way to do color gradients.
