I couldn't take down any lower power machine for these benchmarks... A lower
power single cpu machine would be better for this. Feel free to throw any
other benchmarks at it.

This core2 duo 2.4 GHz with 2GB ram and 7200 rpm 16MB cache hard drive is not
too discrimanatory, but here are the results (use fixed font to see):
