MacBook Pro born again with fresh install

    I just wanted to report that yesterday morning, I was a frustrated MacBook Pro user. While I liked the larger screen, it certainly felt not much faster that my Powerbook G4 1.5Ghz I upgraded from.

    A good example would be Google Notifier. For those not familiar, it is a menu item, simple little piece of software, that lets you know when you have Gmail and allows you to pop open your inbox with your web browser. You open the menu, select "go to inbox" and off ya go. On my Powerbook: 1 second from selection to the page opening and starting to load. The notifier is a UB.

    On my brand new Macbook Pro: 5-10 seconds, IF it would do it at all.

    iTunes, ichat... all would take 10, 15, 20 seconds to load. I was utterly unimpressed.

    So, having opened the box and eagerly begun setting up the computer when I first got it, I went back and did what I SHOULD have done in the first place: install the OS and related options fresh from the DVDs. So yesterday I backed everything up, reformatted the hard drive (HFS, no journalling) and reinstalled.

    I am not basically back up to where I was yesterday morning. Apps installed, everything the way I like it, and wow what a difference. Here's the Intel performance I'd heard so much about.

    So I have three theories, which may help some of you who've been frustrated by the speed of your MCP:

    1: Something on mine came "corrupted" on the master image they use to set up the hard drive. A preference was set wrong or something, and it hobbled my MCP.

    2: I got the 200GB hard drive option, and perhaps the journaling was taking this already slower drive and giving it one more thing to do, resulting in the speed hit.

    3: Something in my initial installs went awry and caused corruption on the hard drive, which reformatting corrected.

    I hope that is helpful to someone. I would love to see if someone sometimes can do a speed comparision of a MCP (especially the 200GB model) with and without journalling turned on, just to see if there's a difference.

    I suppose there are many other bottlenecks other than just the processor, like the hard drive.

    Why turn off journaling?, what performance enhancement does that give?

    "When Should Journaling Be Used?

    Journaling is best suited for servers requiring high availability, servers containing volumes with many files, and servers containing data that is backed up at infrequent intervals (nightly, for example).

    If a volume contains read-only data that is not mission-critical, it may not be necessary to turn on journaling if performance is more important than safety.

    If your server contains high-bandwidth usage data files, such as large video, graphics, or audio files, you may want to weigh the benefits of using journaling against the performance needed to access your data. In most cases, the impact of journaling upon data access performance are unnoticeable to users, but its implementation may not be practical for servers where data access demands outweigh its benefits."
