Question
After receiving multiple complaints from VMware Horizon-based virtual desktop users about their slower logon and application load times, an administrator performed troubleshooting on the issue to optimize the environment. The following discoveries were made on the Nutanix cluster:

Explanation
Of the four findings, 'Failed to create Native clone errors' (Answer B) is the one directly causing slower logon and application load times. Native clones in a VMware/Nutanix environment rely on VAAI (vStorage APIs for Array Integration) to offload clone operations to the storage layer, making them near-instantaneous. When native clone creation fails, VMware falls back to a software-based clone process that is significantly slower and more I/O intensive. This directly impacts how quickly linked-clone or instant-clone desktops are provisioned and how fast the base image is accessed at logon. High Performance power policy (Answer A) actually helps performance. 75% memory utilization (Answer C) is elevated but not critically so. 4% CPU Ready time (Answer D) is within acceptable range and would not cause the described symptoms.
