    應該係 CPU 有安全漏洞, Intel 建議唔好開 Hyper Thread。即  4C/8T 叫你行返 4C/4T。咁舊 notebook i5 2C/4T 得返 2C/2T...

呢個漏洞會導至咩後果?
intel無左HT, i7-->i5

唔係淨係尼個漏洞.
而係 Core 架構本身個記憶體控制器就係靠尼d 捷徑先有咁高性能
HT 功能只係應用尼d 捷徑既方法.
關左HT 唔會令個問題冇左只係影響相對冇咁大.

問題冇fix 到, 但係就一野冇左30% 效能

一定係,除非唔係:

Update, 5/14/19, 1:47pm PT: Added multiple items, posted underneath update note below:

Intel clarified that it's not recommending everyone to disable Hyper-Threading,
but that some of its customers should consider the option depending on their security needs:

"Once these updates are applied, it may be appropriate for some customers to consider additional steps. This includes customers who cannot guarantee that trusted software is running on their system(s) and are using Simultaneous Multi-Threading (SMT). In these cases, customers should consider how they utilize SMT for their particular workload(s) .........
