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), guidance from their OS and VMM software providers, and the security threat model for their particular environment. Because these factors will vary considerably by customer, Intel is not recommending that Intel® HT be disabled, and it’s important to understand that doing so does not alone provide protection against MDS. 下面的FAQ Is Intel recommending that I disable HT? No. Intel is not recommending that users disable Intel® Hyper threading. It’s important to understand that doing so does not alone provide protection against MDS, and may impact workload performance or resource utilization that can vary depending on the workload. --- Intel: 我們不建議你直接關HT 這要看你的環境,先去問問你OS/虛擬機服務提供商的建議吧 (甩鍋) -- <(┘╴└)>﹍﹍﹍ ︿︿ ╴▅ 生命,就該浪費在 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 60.250.75.122 ※ 文章網址: https://www.ptt.cc/bbs/PC_Shopping/M.1557994400.A.94C.html
