Enables the NUMA interleave memory policy for allocation of the InnoDB  buffer pool. When innodb_numa_interleave  is enabled, the NUMA memory policy is set to MPOL_INTERLEAVE  for the mysqld  process. After the InnoDB  buffer pool is allocated, the NUMA memory policy is set back to MPOL_DEFAULT . For the innodb_numa_interleave  option to be available, MySQL must be compiled on a NUMA-enabled Linux system. 

CMake  sets the default WITH_NUMA  value based on whether the current platform has NUMA  support. For more information, see Section 2.9.7, “MySQL Source-Configuration Options” .

Specifies the approximate percentage of the InnoDB  buffer pool used for the old block sublist. The range of values is 5 to 95. The default value is 37 (that is, 3/8 of the pool). Often used in combination with innodb_old_blocks_time . 

For more information, see Section 15.8.3.3, “Making the Buffer Pool Scan Resistant” . For information about buffer pool management, the LRU algorithm, and eviction policies, see Section 15.5.1, “Buffer Pool” .
