I can certainly confirm that, in my Linux VM.  No lag on the small 
mandelbrot, but quite noticeable lag on the big one.  No visible lag on 
either one on the host OS (Mac).

I hadn't gotten past confirming yet, but _something_ is going on there. 
  My guess is painting, though that doesn't explain why you don't see it 
in the Ubuntu builds....

I believe 64-bit jit will happen in Firefox whatever-is-after-3.6.
