leopard 10.5.8 on a dp 1.25mhz mdd with 2 gigs of ram, any tweaks that you would suggest, any ways to go about kernel hacking and trimming my system?
You looking for better cpu performance, i/o performance, or just more disk space?
If you don't regularly use all your installed ram, how 'bout a RAM Disk? What speed HD you gots? WRT externals, keep in mind that FW is far less cpu intensive than USB.
im trying to make it ultra-snappy and everything that doesnt need to run or be loaded, needs to be killed. So any ideas?
OS X is quite thrifty. It already only loads what it needs, and even then mostly not until it's actually needed. About the only thing that can slow it down is stale or corrupted caches. An app such as AppleJack can fix that easily.
If you're ok with making future updates (system and app) more complicated, you can rip out unused languages and template files. That won't save you any cpu time, but it will save some disk space. ...As I recall, GarageBand's library is gigantic!
There are things that can be done to individual apps. eg: Use Perian instead of the regular divx codec. Use VLC instead of QuickTime Player (Apple's codecs pretty much suck). Install appropriate ad and Flash blockers in all your browsers. ... It would help if you mentioned your actual app mix.

and turn off journaling.
sigh. HFS' journaling feature can be a pig - using up as much as .01% of your CPU and about as much i/o bandwidth. Perhaps a bit more when you make BIG changes to your file system (like moving or deleting hundreds/thousands of files). Be sure to keep a bootable DiskWarrior disk around ($99?), of course --- without journaling, a simple power hit can fark your file system way beyond fsck's (Disk Utility) ability to fix it. heh. sigh. Journaling is one of the most efficient triumphs Apple has added to our HFS file system in 15+ years. Don't shoot yourself in the foot.
You'd be better off ditching things like Dashboard. a big memory pig, if you don't use it.
