BalanceBias		REG_DWORD 0 - 0xffffffff		(0 = default)

After all load balance calculations are done, BalanceBias is added to the resulting load level. An idle system has a very small load level, a busy system a larger load level. By specifying a positive number here, a system can be made to look busier than it actually is. By specifying a negative number (for example, 0xfffffff0) a system can be made to look less busy.

BalanceMaxPageFaults REG_DWORD	0 - 0xffffffff	(1000 = default)
Specifies the maximum number of page faults used for load balance
calculations.
BalanceMaxUserLicenses REG_DWORD	0 - 0xffffffff	(10 = default)

By changing this value, the maximum number of user licenses used for load balance calculations can be limited. Load balance calculations use the lesser of BalanceMaxUserLicenses and the number of installed user licenses. Load balancing will never select a system that does not have at least one available user license.

BalanceMemoryLoad REG_DWORD 0 - 1000(100 = default) Specifies the memory load weighting factor. Each of the weighting factors is divided by the sum of the weighting factors to arrive at ratios that are used to compute the system load level. The memory load is calculated by the following algorithm:

if (available memory pages < 100) then memory load = 100 * memory load ratio

else

memory load = (100 - ((available memory pages - 100) / 10))* memory load ratio

Increasing BalanceMemoryLoad gives more “weight” to memory load in computing the load level. Setting this value to 0 causes load balancing to ignore memory load.

BalanceMinPageFile REG_DWORD 0 - 0xffffffff (500 = default) Specifies the minimum number of free bytes that must be present in the page file for load balancing to select the system.
