Interesting... my L2 cache is much faster
I too have been struggling with my (3 day old) iMac G5 20" and why it seems so "slow". Thanks to this thread, I adjusted my power properties to high performance. That definitely helped.
The place I see the slow performance is in scrolling. iTunes, with 2905 songs, was very slow to scroll versus my PC (set up next to the mac). The power properties helped a lot with that. However, Word is still very choppy when scrolling through documents on the Mac, while it's super-smooth on my 2.4 GHz PC w/ 1 GB of RAM.
My G5 does only have 512 MB. I can see the CPU maxing out on the activity monitor when I scroll through documents (and when I scroll through iTunes).
Any ideas about that?
Very interesting: when I ran xbench, it reported a 1.8 GHz L2 cache versus the 1.15 GHz cache others are reporting. Is this a new thing?
