I recently got a 400mhz pismo with 384mb of ram and a slow, 6GB hdd drive. I run Tiger on it and i use it for basic work, like web surfing, word procesing and some light web development. I just started a mission to make this computer as fast as possible for this type of work. This is what ive done so far.
- I disabled dashboard to free some ram
- I removed all printer drivers and localization in OSX to get some more disk space (I just gor a new 40gb hdd. They are very cheap and performance boost from faster hdd is huge. Its also nice to have all your data in one place.).
- I removed font smoothing. It is uglier, but you get used to it and scrolling is MUCH faster. Safari is now actualy plesat to surf with even on large sites.
- I used TinkerTool to disable some gfx effects like gennie effect, dock animation etc.
- I boosted keyboard repeat speed an mouse tracking speed. You can do that in system preferences under "Keyboard and mouse". When i first read that tip i didnt even want to try it because it sounded stupid to me, but in fact it helps alot in general snappines.
- I used Aticcelerator II to overclock gfx card (cpu 140mhz / ram 120, maybe i can go even higher). I also boosted cache speed from 160mhz to 200mhz (it should go up to 267mhz in pismos but mine is crashing with that settings. Not much improvement there, but better something than nothing).
Thats about it. I also tried shadowkiller to remove shadows but performance boost wasnt that big and i find shadows useful. Im also experimenting with themes to remove transparency, but dont want to change the system too much since i like the way OSX looks. Not a big performance boost either...Aqua stays.
The only benchmark i used is a "let 1k windows bloom" proggy that opens and closes 1000 windows. You can find it on google. I managed to get the results around 35 seconds with these settings, even few seconds less with shadowkiller. Thats is more than 100% improvement over stock Pismo 400. In real world my computer is now not only usable but very plesant to work with and OSX still looks very nice.
I hope that helps
Other than that i just finished repacking my dead battery with new 2000mah cells so i should get 5, 6 hours of battery life (on my first charge cycle i got more than 3 hours). Im also planing to install internal bluetooth and internal airport card
