Well something happened here. The tuning under IO load has relaxed the 
pressure even more to allow kernel compilation to proceed. Mem load seems to 
have changed dramatically though with a disproportionately long increase in 
kernel compilation time given only a modest increase in the amount of work 
done by mem load. Process_load seems proportionately longer than mm1 with an 
appropriate rise in load work done. 
 
Below are also the experimental results with the newer loads:

These do not appear significantly different.
