Any updates on this issue? I have a similar problem with my MBP i7
I just installed a vertex2 (120gb) SSD and was getting 13 second boot times with a fresh install of 10.6.3, then immediately after I updated to 10.6.5, boot times are now 23 seconds.
I reset the PRAM, permissions repairs, many reboots, and left the computer on all night long, still constantly 23 second boots.
I'm thinking of formatting my SSD again, and just sticking with the fresh 10.6.3 install.
Any advice would be greatly appreciated.
Thank you
