Regarding the z9, does anyone have a view on running subcapacity engines 
vs. full capacity engines?

For example, considering the following:
z9-508 has 352 MSUs (2613 MIPs)
z9-705 has 363 MSUs (2633 MIPs)

The 705 is using 5 full capacity PUs and the 508 is using 8 subcap PUs.

Is there any noticeable difference (aside from the slight diff in MSUs) ?
Is this similar to "shorting an engine" like you can get with logical vs. 
physical 
assignments in PR/SM?

Thanks,
Dave
