    Like the title says the MacBook Pro from last year boots faster than my 2x2.93 Mac Pro w/ HD5870 which arrived yesterday. Both machines have 8GB of RAM. Can anybody explain this?

    Did you install anything yet? Does either machine have an SSD? We need more information.

    do you have eight 1gb sticks of ram in the dual cpu 12 core vs 2 4gb sticks of ram in the macbook pro?

    It's normal for a Mac Pro to have a longer delay before the chime, which can delay boot time.

    That is exactly the case. Once it's on its a screamer! The RAM is configured 4x2GB unbuffered ECC 1333MHz, the laptop is 2x4GB 1066MHz. The hard drive in the Mac Pro is a 2TB 7,200 and the MBP has a 500GB 7,200rpm drive. I was thinking that it takes longer to feed power into the components in the Mac Pro like the GPU with a built in fan, etc.

    The fastest booting Mac in my house is my ancient Macintosh SE/30 (which has a newer SCSI hard drive in it - so new that the hard drive is faster than the SCSI interface on the SE/30.) Boots way faster than any of my Intel Macs. In fact, when booting System 6, it boots to the desktop before the CRT has warmed all the way up.

    Just because the machine has a faster processor doesn't mean squat about boot time.

    Yeah I'd kinda put it as boot up being "stretching before a race", being ready first doesn't mean you'll be the first across the finish line..

    Hope that made sense, lol.

    Yeah - more hardware = longer POST time.

    Ask me about the 15k that took a half hour to boot.

    I had a similar question a while back. I was told there is some preliminary system check throughout the system before the chime. So basically, the more stuff you have hooked up to it (HDs, RAM, USB cables, anything really) the longer it takes for the system to go through all of that. I think boot time is better measured after the chime. However, boot times are pretty reliant on read times from the drive, which is why SSD boot times are so much faster.

    Yea the Mac Pro is checking a lot of I/O before loading the kernel.

    Yes, it also depends on the footprint of the OS. I mean, comparing MacOS 6 with OS X Snow Leopard... :rolleyes:

    Not during post. OS is not touched yet. So your new SSD or HD is not a factor. NVRAM resets have been known to speed this up but only by .3 secs or something.

    Yeah, it's the RAM arrangement. I noticed a longer boot time after upping my RAM from 2GB to 4GB.
