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.
