Fixing that will cause a performance decrease overall, as the context switches into the kernel will take longer than previous. That's my crude understanding of the issue.</P> <P>So the systems need to be patched, and the performance penalty evaluated.</P> Thu, 11 Jan 2018 20:32:03 GMT https://communities.sas.com/t5/Administration-and-Deployment/Meltdown-and-Spectre/m-p/427000#M11872 Kurt_Bremser 2018-01-11T20:32:03Z https://communities.sas.com/t5/Administration-and-Deployment/Meltdown-and-Spectre/m-p/427110#M11873 <P>Official statement from SAS...</P><P>&nbsp;</P><P><SPAN><A href="https://support.sas.com/en/security-bulletins/Meltdown-and-Spectre-vulnerabilities.html" target="_blank">https://support.sas.com/en/security-bulletins/Meltdown-and-Spectre-vulnerabilities.html</A></SPAN></P><P>&nbsp;</P> Fri, 12 Jan 2018 05:51:52 GMT https://communities.sas.com/t5/Administration-and-Deployment/Meltdown-and-Spectre/m-p/427110#M11873 nhvdwalt 2018-01-12T05:51:52Z
