engadget 中文版 - 微軟表示安全性更新會明顯拖慢老電腦的速度

以下為軟軟說明：
依照偶們(軟軟)的經驗
修正 Variant 1 & 3 對效能影響較小,
修正 Variant 2 (OS+microcode) 對效能影響較大。

1. Win10 搭配新的晶片(2016 PC 採用 Skylake, Kabylake 或是更新的 CPU)
> 測試程式測試效能表現僅降低個位數; 因此預期大多數使用者無法發現效能有下降的狀況。

2. Win10 搭配舊的晶片(2015 PC 採用 Haswell 或是更舊的 CPU)
> 測試程式測試有部分測試明顯有效能降低; 因此預期部分使用者會發現效能有下降。

3. Win8 與 Win7 搭配舊的晶片(2015 PC 採用 Haswell 或是更舊的 CPU)
> 我們預期大部分的使用者都會發現效能有下降。

原文：
Our experience is that Variant 1 and Variant 3 mitigations have minimal performance impact, while Variant 2 remediation, including OS and microcode, has a performance impact.

Here is the summary of what we have found so far:

1.With Windows 10 on newer silicon (2016-era PCs with Skylake, Kabylake or newer CPU), benchmarks show single-digit slowdowns, but we don’t expect most users to notice a change because these percentages are reflected in milliseconds.

2. With Windows 10 on older silicon (2015-era PCs with Haswell or older CPU), some benchmarks show more significant slowdowns, and we expect that some users will notice a decrease in system performance.

3.With Windows 8 and Windows 7 on older silicon (2015-era PCs with Haswell or older CPU), we expect most users to notice a decrease in system performance.
