42 seconds even if not the final result is nothing compared to my 2ghz Intel Mac Mini which was recently upgraded to Mac OS X Lion (something which I regret atm, so slow and buggy - bad Apple). I went from around 1 minute under Snow Leopard to over 2 minutes with Lion.
Considering 4.1 u2 takes 20-30 to boot cold on a SAM 460 its fine to assume the new Amiga running u3 will pretty much take the same amount of time.
