smpProcessorAffinityMask
Optional uint attribute.Specifies the hexadecimal processor mask for multi-processor
computers,which indicates to which cpu the worker processes in an
application pool should be bound. Before this property takes effect,
the smpAffinitized attribute must be set to true for the application
pool.Note: On 64-bit computers,the smpProcessorAffinityMask attribute
contains the low-order DWORD for the processor mask,and the
smpProcessorAffinityMask2 attribute contains the high-order DWORD for
the processor mask. On 32-bit computers,the smpProcessorAffinityMask2
attribute has no effect.If you set the value to 1 (which corresponds to 00000000000000001 in
binary),the worker processes in an application pool run on only the
first processor. If you set the value to 2 (which corresponds to
0000000000000010 in binary),the worker processes run on only the
second processor. If you set the value to 3 (which corresponds to
0000000000000011 in binary) the worker processes run on both the first
and second processors.Note: Do not set this property to 0. Doing so disables symmetric
multiprocessing (SMP) affinity and creates an error condition. This
means that processes running on one cpu will not remain affiliated
with that cpu throughout their lifetime.The default value is 4294967295.
首先,将smpAffinitized设置为true.
