Possible new optimizing trick
May have stumbled onto a possible way of optimizing OS X Jag. It may sound silly at first but give it a try. I can honestly say my iBook 500 has never run this well since I initially got it in June 2001 with 10.0.3. I have never done a clean reinstall. I have always taken the simple upgrade approach which I recently did again with 10.2.1. Here goes.
Download the 10.2.1 updater from Apple. Update your computer even if you already have 10.2.1. Restart your computer.
Do this 2 or 3 more times, restarting each time.
Then, insert your 10.2 install disk 1 and boot from it. (Do not install anything.) Go to the menubar and open disk utility. Run fix permissions. When this is done restart.
If your results are like mine, you will notice a difference.
I did not come up with this potential solution. I found it in an Apple discussion forum regarding a different topic.
It may appear redundant and it may very well be. Give it a try if you have a little time. You just may be surprised.

Be skeptical, that's fine. It did work for me however.

I'd love to speed up this 600Mhz iBook but I'm afraid to do anything too radical. Why don't some more of you folks do this first and let me know how it works??

Previously I fixed permissions when booted in OS X. This was the first time that I used the installer disk to do it. Could be this is what helped.
Updating over an update is risky? I did it on both of my computers with absolutely no problems. I think it might be some kind of super binding. But then again, I have no idea. I don't think there is much here that could hurt either.
Over the last year and a half, I have downloaded, tried and thrown away a lot of software. I have done a lot of iMovies that pretty well filled up my 20gig internal hard drive. Constantly moving these on and off my iBook.
I have seen some slowdowns over this time and strongly considered a clean install for Jag. Didn't want to take the time and did the simple upgrade.
This trick helped me. Your mileage may vary.
I have never heard Apple reccommend anything but caution and the correct order on installations of systems and system updates.
If it helps at all, I'm surprised you found this information on Apple's site.
My system is fast enough, thank-you....

There's no fancy trickery here and it has nothing to do with prebinding. There's no reason to wait before trying it. This simply scans ALL files on the drive, fixing the permissions and ownership on any that are incorrect. Specifically, files that have dab permissions are probably ones you've put in /Applications and /Library and sometimes the ones in /System if you've added some kinds of hacks.
I've been suggesting this for months, since the Repair Permissions utility was released for 10.1. I'm surprised you guys are just now catching on.
I don't understand why running the 10.2.1 updater over an installed 10.2.1 system would have any effect: isn't it just going to run through, check everything that should be there for 10.2.1 is present and correct, then pre-bind it? Anyone got any light to shed on this?

<strong> Unlike the "repair disk" part of Disk Utility, the "repair permissions" CAN be run on the startup drive.</strong><hr></blockquote>
AFAIK it can only fix permissions on the startup drive, so booting from CD won't fix your HD.
cheers.
<strong>By the way, you do not need to boot from the install CD to do this. Running Disk Utility from your hard drive does the exact same thing. Unlike the "repair disk" part of Disk Utility, the "repair permissions" CAN be run on the startup drive.

Well if Brad says it's ok to do then it's ok and I'll do it
