Use 128 bytes as the start size region to be same to previous one. 64 bytes is small as the first range. On X64 arch, POOL_OVERHEAD takes 40 bytes, the pool data less than 24 bytes can be fit into it. But, the real allocation is few that can't reduce its free pool link list. And, the second range (64~128) has more allocation that also increases the free pool link list of the first range. Then, the link list will become longer and longer. When LinkList check enable in DEBUG tip, the long link list will bring the additional overhead and bad performance. Here is the performance data collected in our X64 platform with DEBUG enable. 64 byte: 22 seconds in BDS phase 128 byte: 19.6 seconds in BDS phase Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Liming Gao <liming.gao@intel.com> Reviewed-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Reviewed-by: Michael Kinney <michael.d.kinney@intel.com> |
