2.5.38-mm1              92.97           77%

As you can see, 2.5.38 is improving in most areas. 2.5.38-mm1 has excellent
performance under mem load now, but exhibits significant slow down under full IO
load. 

To reproduce full IO load, continuously copy /dev/zero in Ram sized chunks to
the same disk and conduct a kernel compile on that disk and time the kernel compile.
