Using this setup, you are able to see the maximum Read and Write performance from a Standard_D8ds_v4 VM. Configure host caching as "ReadOnly" on the remaining disk and create a volume called CacheReads with this disk. Of the four disks, configure three with host caching as "None" and stripe them into a volume called NoCacheWrites. To follow the examples below, create a Standard_D8ds_v4 and attach four premium SSDs to the VM. To learn more about each benchmarking tool visit DiskSpd and FIO. ![]() This gives you more flexibility to drive the maximum performance on a high scale VM provisioned with premium SSDs for different types of application workloads. Using the tools you can also configure parameters like block size and queue depth, which you normally cannot change for an application. These tools spawn multiple threads simulating a production like workload, and measure the system performance. ![]() We have used common benchmarking tools DiskSpd and FIO, for Windows and Linux respectively. In this article, we provide you examples of benchmarking a Standard_D8ds_v4 VM provisioned with Azure premium SSDs. By running benchmarking tools on the VMs hosting the application, you can determine the performance levels that your application can achieve with premium SSDs. Using the steps described in the designing for high performance article, you have gathered the application performance requirements. Applies to: ✔️ Linux VMs ✔️ Windows VMs ✔️ Flexible scale sets ✔️ Uniform scale setsīenchmarking is the process of simulating different workloads on your application and measuring the application performance for each workload.
