For adaptive partitioning to operate properly, your system should meet these requirements:
On x86 systems, turn off any BIOS configuration that may cause the processor to enter
System Management Mode (SMM). A typical example is USB legacy support. If the processor
enters SMM, the adaptive partitioning thread scheduler continues to function correctly, but
CPU percentages apportioned to partitions will be inaccurate.
A typical reason for preventing SMM is that it introduces interrupt latencies of about
100 microseconds at unpredictable intervals.
