BalanceBias REG_DWORD 0 - 0xffffffff
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
Specifies the maximum number of page faults used for load balance
calculations.
BalanceMaxUserLicenses REG_DWORD
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
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
Specifies the minimum number of free bytes that must be present in the page
file for load balancing to select the system.
