I think top only has a reasonable view of the world when running Linux native i.e. no z/VM and the IFLs are dedicated to the lpar i.e. not shared with another lpar. Otherwise various virtualization effects come into play which make the top numbers rather meaningless without a means to prorate them according to outside info.

This LPAR has 4 IFL's installed and the Linux has access to all four. Can we use the %cpu below 400 % as an indicator that we are not using all four at that moment? Also if the %cpu says lets say ... 382% are we using 100% of two CPU's and 82% of the third maybe? Any input or ideas here would be great.
