Performance of SOLIDWORKS after applying the patch Specter and Meltdown

DS SOLIDWORKS is performing extensive testing in an effort to determine the potential impact of any solutions that are issued to mitigate the Spectre and Meltdown vulnerabilities.
The SOLIDWORKS Knowledgebase solution S-074167 discusses the potential effect on performance upon systems that have employed the Microsoft® Windows® Update security patch released on January 9th, 2018 that was intended to address the Spectre and Meltdown vulnerabilities.

DS SOLIDWORKS intends to report the results of their ongoing tests at SOLIDWORKS World (Feb 4th – 7th 2018). The report will likely be relayed to reseller staff and further updates can be expected by our customers during the second week in February.
