Hyper-V Disk Speed Musings

Hyper-V Disk Speed Musings

I was testing out the Intel 905P and getting the benchmark numbers, I also went ahead and installed HyperV, set it up correctly, and then created a Windows 2016 VM running and decided to run the same CrystalDiskMark benchmarks again, in the HyperV host as well as inside the VM. I only had the one …

For reference, this is a PCIe add in card (4x lanes) that uses the Intel/Micron 3D XPoint (or Optane) memory instead of the usual NAND flash.  The promise is really high random performance at low queue depths. For these benchmarks the server config is: …

Recently I had the opportunity arise where I was able to test a few CPU core configurations on an unused host. My gold here is to see if a CPU virtualization penalty exists and secondarily to see what effect hyperthreading has on CPU performance in a single VM setting. Specs of the host:  Dual Xeon …

To recap, here’s the full 16 physical/32 logical benchmark: And now, hyperthreading disabled: And there we go.  Hyperthreading adds …

Clearing AX Client Cache for One User in a RDS Environment Using Powershell

“You should clear that person’s AX cache”. How many times have you heard that?  If you are running Dynamics 2012 (R2 in my case), this post may help. Let’s start with some assumptions. You have the AX client deployed using Remote Desktop Services (RemoteAPP) You are not using User Profile Disks You have multiple RDS …
