You may know that VMware vSphere offers several types of SCSI adapters for virtual machines depending on the OS. The main types are "LSI Logic SAS" and "VMware Paravirtual". There are a lot of articles on this topic (e.g. https://blogs.vmware.com/vsphere/2014/02/vscsi-controller-choose-performance.html). But the real comparison of the performance I saw once, but it's a bit outdated (ESXi 5.0 and Windows Server 2008R2).
Therefore, I did my tests (although not on the latest versions of OS) and compare IOPS, Latency and CPU usage. As a load generator used IO meter 1.1.0.
