Very similar machine to yours, Hans, except a little slower (MBPro 2
GHz. OS X 10.4.10)
19 ms. -- 0.49.3-extended-20071108
19 ms. -- 0.40.3-extended-20071011
17 ms. -- 0.39.3-extended
I'm curious what effect the dual-core is having on this, too. I thought
I had chud loaded (Apple xcode tool to switch off a core), but I don't,
and can't find the damn xcode tools disk. If I do, I'll post results w/
one core.
