Version 4.0.3 (6531.9, r50006)

CPU usage is spikes between 30...98%
User input is delayed about a second
Load time takes 12...14 seconds, then animation begins after another 1 minute
and 55 seconds

I have compared this performance with the current version of FireFox.  
Load time about 2..3 seconds
Animation begins immediately
CPU usage 3...7%
User input is instantaneous

This problem has existed for a couple years.  In that time there have been
hundreds of updates, none have affected this problem.  I think this is a core
design issue rather than a faulty routine.

This problem is still marked unconfirmed... Load this URL

minutes, realized while waiting for animation to begin.  30 seconds more to
confirm the scrolling problem.
