The graph is a bit confusing because you essentially need to compare the two inner bars, and the two outer bars. It might be clearer with the 2 x86 setups adjacent, and the 2 ppc setups adjacent. It's also a bit unclear to me whether high values are universally good, or low values, or whether it varies from test to test. From what I could find, it looked like high was good for file copy and low for the rest, but maybe they've been modified so high is always good. Could you provide some more detailed hardware specs and `emerge info`? I'd really like to put this data up somewhere on gentoo.org/proj/en/cluster/ -- with your name etc withheld if necessary. It would be interesting to do some performance analysis to see where any slowdowns come from and try to get things up to speed. Thanks, Donnie
