I see the brilliance in POWER7 and the step forward that POWER7 offers as a platform over the legacy z/OS-centric hardware.
That's jumbled word salad once again. Alternatively, it's so patently obvio ... |

Well, hopefully the superb resources still left at that client will read this and do the same. I have since moved to a greener pasture.

If the WMB message flows are CPU inefficient it's generally cheaper to throw P-series boxes at it.
No, it's generally cheaper to throw some hours at it and address the inefficient flows. Then, regard ... |
