You can enable read optimized cache on CSV disk on Hyper-V v3.
However there is no such option on GUI to enable CSV Cache, so you should go with Powershell.

I set 4 GB memory for CSV Cache allocation: (by default, it’s 512 mb)

(Get-Cluster).SharedVolumeBlockCacheSizeInMB=4096

Then I need to enable CSV cache on clustered disk:

Get-ClusterSharedVolume "Cluster Disk 1" | Set-ClusterParameter CsvEnableBlockCache 1

I want to show you my test results with different cache sizes.
