BDW-E完全消失了 卧槽，还想着换win7，win7打补丁性能下降更严重？微软你要脸不 打倒恶霸微软，大家一起用Linux
M$B,年后换农企 明明是intel的问题，结果你们在这儿喷微软... scad 发表于 2018-1-10 13:48
讨论的重点是这两段话
这篇文章只提了旧操作系统受影响更大的事实，而没有提为什么 （仍然是intel的锅 说实话家里的主力台机真心不想换win10，东西太多升级完肯定很多兼容性出问题太麻烦了 妈的，intel好不容易挤的牙膏，又tm嫌挤多了吞回去了 才注意到好久都没更新过的win7今天居然自己更新了补丁。 我擦，怪不得今天用着用着就卡死了好多次 yzyzlhtsdw 发表于 2018-1-10 14:01

文章里明明就有解释的好不好不过这楼里的人都忙着带节奏强行无视了
win7/8里在设计上落伍，用户态到内核态的切换频率比起win10更高，所以受到的影响更大
所以说标红是们学问
Here is the summary of what we have found so far:
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.
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.
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.
Windows Server on any silicon, especially in any IO-intensive application, shows a more significant performance impact when you enable the mitigations to isolate untrusted code within a Windows Server instance. This is why you want to be careful to evaluate the risk of untrusted code for each Windows Server instance, and balance the security versus performance tradeoff for your environment.
For context, on newer CPUs such as on Skylake and beyond, Intel has refined the instructions used to disable branch speculation to be more specific to indirect branches, reducing the overall performance penalty of the Spectre mitigation. Older versions of Windows have a larger performance impact because Windows 7 and Windows 8 have more user-kernel transitions because of legacy design decisions, such as all font rendering taking place in the kernel. We will publish data on benchmark performance in the weeks ahead. 那这是不是可以完全解释为什么win10天生性能不如win7了
