Emulation
Guides on emulating older applications

Available only to registered hardware & software developers, Apple's Computer Hardware Understanding Developer Tools (CHUD Tools) were designed to allow you to effectively measure and optimize the performance of PowerPC Mac systems running Mac OS X.

This is basically a must-have for you, if you have a dual CPU Macintosh as it enables "napping". Enable Nap allows the processors to coast when not under heavy load which can decrease temp by 20F degrees without loss of performance.

Note: This feature is enabled by default on single processor machines, so is not needed.

1st download: CHUD Tools 3.5.2
2nd download: An AppleScript that automatically enables Nap at startup on dual processor MDD machines. Doesn't work with OS X 10.5 Leopard. (see included readme for details)

Compatibility
Architecture: PPC

Requires Mac OS X 10.2 or later.

This is not for Tiger nor Leopard. It allows you to install it, then it feeds a few gremlins after midnight (gmt). Tiger and Leo need suite v4.0 or greater.

Another error in the description, Nap mode is never enabled by default even on 1CPU systems. Specific versions of OS 9 and OS X extensions will enable Nap, but if you run AHT, Open Firmware, or just sit there at the Multi-boot or OF Password prompts, then Nap mode doesn't become enabled and you are frying your machine in a wok.

Definitely go with CHUD v4.x on Tiger. And use the CHUD Remover to scrub off this'un. I'd even run several versions of CHUD Remover to make sure you get it all gone.

I had a weird issue with this when I tried it on my MDD running Tiger. For some reason it caused constant hard disk activity. So I ended up removing it.

The enable nap feature helped me to lower the temperature of my dual CPU MDD by an average of 3-4° C. That's pretty amazing for a "software solution". Not to mention the MDD fan noise got less, so highly recommending it if you're owning a dual CPU MDD and OSX.
