Don’t Let The Spectre Ghost Haunt Your User Experience !
Due to the nature of the vulnerabilities and how they work, patching against Spectre and Meltdown will likely have an effect on the performance of your environment.
Knowing the impact of these patches on your systems is essential, The repercussions of reduced performance on your existing hardware could have a detrimental effect on end user experience, applying these updates without testing their impact could be disastrous, causing systems to be sluggish or no longer been able to handle expected user workloads. Some of the early testing shows a performance related reduction of 5% of user capacity after applying Microsoft recommendations, the impact of this could result in additional hardware investment to meet expectations of a pre Meltdown/Spectre environment.
Systech IT Solutions with LoginVSI are offering a free for end user businesses, “Emergency Edition” of LoginVSI until 31st of March 2018 to help gauge the potential performance impact caused by patching these vulnerabilities.
Performing tests with LoginVSI in advance, will provide valuable information to make sure your environment will still provide the same end user experience.
LoginVSI works by simulating how a real users use your environment and produces statistics to make performance comparisons easy to understand. The same performance test can be run on the environment before and after patches have been applied, this will show you the real world impact of the patching on your systems. The expected results related to Spectre and Meltdown should show a reduced capacity on the same hardware as CPU load is expected to increase.
