Greetings...I just purchased a 2011 15" 2.2 ghz i7 quad core Macbook pro with the 500 gb 7200 RPM hard drive. I upgraded it to Lion (via a free download from apple). It takes 1:40 seconds to boot to a server login prompt !!?? I don;t have the boot time from when the MBP had Snow Leopard installed to compare to. I checked other forum posts and I am seeing some times of 40 seconds with 5400 rpm drives on 13" i5 & i7's...so it seems to me my boot time is slow. 2 questions: Do you think the Lion upgrade is slowing down the boot? Do you think I should do a clean Lion install (I created a bootable DVD via the InstallESD.dmg image I saved based on a MR forum post)? Any thoughts, comments, or additional suggestions is appreciated.
