我想睇分,點解唔POST埋上黎
14 percent performance hit on Coffee Lake, and a nearly 20 percent performance whack on Broadwell-E. Redis performance (not pictured) was down about 7 percent on both systems.

ComputerBase.de has some early benchmarks as well, mostly showing that the impact on user space applications (most consumer apps) is minimal. There may be a very small performance hit on the order of 2-5 percent in some games, but this is not an absolute.

然後日常使用上,大部份性能差距 下降近0
(因為INTEL有另一組名為PCID的硬體處理系統去處理這方面的問題,
由93年開始引入至今,不過LINUX修補檔並沒有啟動PCID,反而WINDOWS和MAC OS,UNLX有)
但係數據中心應用就差好多,唔知有冇優化空間

二師兄

係咪windows update 一定要install 呢個patch?
