The goal of this test plan is to test SPECTRE and MELTDOWN performance impact on Intel CPU. We will run CPU intensive workloads in Virtual Machine(s) running on non-patched and patched ESXi host and observe performance impact.
We will test impact on network, storage and memory performance because these I/O intensive workloads requires CPU caching which is impacted by vulnerabilities remediation.
Qualification of performance is very specific and hard subject. The performance impact varies across different hardware and software configurations. However, performed tests are very well described in this document so the reader can understand all conditions of the test and observed results. The reader can also perform tests on his specific hardware and software configurations.
