Analyzing the Performance Effects of Meltdown + Spectre on Apache Spark Workloads

Download Slides

Meltdown and Spectre are two security vulnerabilities disclosed in early 2018 that expose systems to cross-VM and cross-process attacks. They were the first of their kind and opened up a new class of exploits that allow one program to scan another program’s memory. The kernel and VM patches released to address these vulnerabilities have shown to degrade the performance of Apache Spark workloads in the cloud by 2-5%.

This talk will dive deep into the exploits and their patches in order to help explain the origin of this decline in performance.
