Good question.. I guess it would too much to ask of them to try to 
figure out what area the problem lies in (even to the point of figuring 
out if it's a CPU or IO-bound problem), or try to bisect, or at least 
report it to LKML before going to the trouble of creating 5 pages of 
graphs.. Given the 20x slowdown in some of the benchmarks you'd think it 
wouldn't be too hard to narrow down.
