Microsoft: CPU bug updates to significantly slow down some servers

While Intel downplays the performance impact of the patches for the Meltdown and Spectre vulnerabilities, Microsoft just send out a statement that indicates the performance slowdowns could be more substantial than Intel has indicated. Especially some server jobs may see a noticeable impact, but users of older PCs with Windows 7 or 8 are also expected to see noticeable performance decreases:

Microsoft cautioned in a blog post that servers, the computers that underpin corporate networks, used for certain tasks may show "more significant impact." Not all servers will be affected, it said. Microsoft, which didn’t provide specific numbers, said it is testing a variety of systems and will update users on what it finds.

PCs running Windows 10 and sold since 2016 will face slowdowns of less than 10 percent, which Microsoft said will probably not be noticeable to users. Customers with older Windows 10 PCs will notice some slowness because those machines contain older chips. Machines running Windows 7 and Windows 8 from 2015 or earlier will be the most affected with users noticing a decrease in system performance, Microsoft said.
