Just stopped by the Apple store to check this on a store riMac (i5) power-on to chime is about 2 seconds (power-on to log-in, 22 seconds). My riMac (i7) has an additional (10s) delay, so chime takes 12 seconds and log-in 32 seconds. Also, let an Apple store employees talk with a genius and he recommended an SMC reset. He also indicated that I should worry not about it (he was also helping others, so it's unlikely he fully understood the issue). Talked with Applecare earlier in the week and the person indicated that the chime should occur almost immediately. He also had me try changing a power saving setting, that seemed to help with a sleep issue. This has occured over several days and doesn't seem correct. Everthing works well otherwise. .
