In 2018 a new class of previously unrecognized vulnerabilities in modern CPUs was recognised by Google and others. Patches for the issues for most operating systems and cloud environments were rapidly produced. These patches came with vaguely stated performance overheads of between 5 and 30%. This presentation outlines the nature of the threat and the approach we took to assessing the likely impact on our database servers, as well as representative application performance benchmark details. Whilst the case study is focussed on a specific technical change, attendees will learn techniques suitable for assessing the performance impact of a large number of platform changes.
