I'm curious about this. My Mac mini has hyperthreading, so this flag
should be helpful.

Once I get the machine back, I can do some simple benchmarks to see. Dave |

I didn't do anything, it just worked that way.
I had to return the machine, because it wasn't reliably using the second
memory bank. They decided it was defective, so I'll get a different
mainboard in a few days.
The problems I experienced with the Mac Mini Duo with the kernel patch I
downloaded last week:
- The video seems to start a few lines down. I can use it if I specify a
height a bit less than my real height (I used width:1600,height:1192).
- No sound output. The driver loads fine, but no mix/configuration
settings seem to make any sound.
- Fully unaccelerated X. Oddly enough, the unaccelerated X server
performs better (x11perf) than my 2.2Ghz AMD64 (32-bit mode) with an
nVidia GeForce FX 5200. Things like scroll500 are nearly twice as
fast. Must be a consequence of the CPU having better access to the
video memory (shared with GPU).
- I built 'mplayer'. Amazingly, with -zoom, it can play movies in an
unresized window. I've never had a machine that could do this. It
can't keep up if the window is made larger. Obviously, this should
work fine once HW scaling is available.

After building my own kernel and installing onto my mac mini, I think that the Ubuntu live CD just uses an aggressive CPU scaling rules set, which doesn't use the full CPU unless necessary. My machine is currently using all of both CPUs, but with the Live CD both were mostly around 1GHz. -- Erik |
