CALayer renderInContext: performance

renderInContext: can be reeeeally slow (2 seconds to draw a tree into a context). It seems that every CALayer is rendered using a Quartz transparency layer, and I know they're slow from past experience. I'm basically just firing off this email to ask if there's a method to make it a lot faster, or something else I could be doing. Everything that's being drawn (about 80 layers), was previously drawn using Quartz very quickly, so I'm hoping there's some way to force renderInContext: to ditch transparency layers or something.
