4 - Way Quad Core, 16 Processors, DONE.

Tonight is the fail over from 4 way dual core to 4 way quad core.

Interesting suttle changes as well, the dual core is AMD NUMA Architecture, the Quad core is Intel - NON NUMA.

Interesting to see, how the machine handles the load.  The current SQL Server is maxed out, all cpu's hitting 100% for sustained times, 4-6 hours.  Very little locking and blocking or disk i/o, all waits are on the SOS_SCHEDULER_YIELD.

Very difficult to recreate this issue or test in the lab, so the results are due tomorrow !

exhaustion.
