Hi,

Can you give me a suggestion to increase disk performance of virtual machine?
I changed the VM size from B4ms to D4s_v3 and disk performance in IOPS is the same.
Why ?

Hi, thanks for the post.

I think its due to Disk IO capping. what's your Disk capacity and tiers. ?The disks have their own IOPS and throughput limits.

Go though this article, it cleanly explains about the VM and DISK IO capping and how it works.
