Explanation

CPU Ready time measures how long a virtual machine's vCPU had to wait before being scheduled on a physical CPU. When the ESXi host power policy is not set to High Performance (B) - for example, if it is set to Balanced or Power Saver - the host's CPU cores may be running at reduced frequencies or sitting in lower power states (C-states). When a VM needs CPU cycles, the host must first ramp up the CPU to full speed, introducing a delay that shows up as CPU Ready time. This explains why desktops on that one host are slower while others are fine: the power policy setting is host-specific. High Performance enabled (A) would actually improve performance, not degrade it. Inline Compression (C) and Erasure Coding (D) are storage-layer features that do not directly cause elevated CPU Ready times.
