I just bought a used iBook (600 mhz combo drive). I'm trying to strip it down as much as possible to run quickly with the longest battery life. I've done all the usual power conservation things: energy saver, dim the lcd, no cd's in the tray. In 9 I've pulled all the extensions and control panels I can. The only programs I intend to use on the laptop are: SimpleText, Terminal/NiftyTelnet, Safari/WebBrowser. I can run either 10.2.8 or 9.2.2. What I'm really looking to do is minimize the hard disk spin-up as much as possible. I looked into RAM disk, and I could get some things in RAM disk in 9, but found that iCab kept accessing the hard drive (presumably for preferences). I had the programs and the cache stored in the RAM disk. Not good enough. In X, the hard disk spins up a lot. I did use "pmset" to make the HD spin down after two minutes, but not enough (man pmset if you're interested). Safari also pulls up hard disk a lot. How do you make either 9 or X work with the least amount of HD spin? This might involve removing daemons and scripts in X that do regular logging. Thanks. Oh, and if you're interested, I found a great script to check the battery's info (this poor battery's at about half-factory) here.
