Performance or protection? How Microsoft patches against Meltdown and Spectre influence CPU, RAM and Disks performance

In today’s topic, I’d like to talk about the Meltdown and Spectre vulnerabilities. But not about the harm they cause, this has been covered widely in numerous articles, but how Microsoft patches intended to protect you from the vulnerabilities, affect (if they do) the hardware performance. Before we take a deep dive into the tests and numbers, let me tell a few words about Meltdown and Spectre and outline the testing scope to make sure we speak one language.

Who’s got bigger balls? Testing NFS vs iSCSI performance. Part 3: test results

In the previous parts, I’ve shown you the process of configuring NFS and iSCSI protocols between our servers. So now, we’ve got everything ready for running our performance tests and finally finding out which network protocol is faster as a storage for virtual machines on VMware ESXi: NFS or iSCSI.

So to benchmark the iSCSI performance, I’ve created the StarWind device on the server and connected it to the ESXi host over the iSCSI protocol. As to OS for running further tests, I’ve used Windows Server 2016.
