The performance statistics indicate that the SSD Cache tier is 85% full, which is the primary bottleneck. In a Nutanix cluster, the SSD tier serves as the high-performance "Hot Tier" (Extent Store and Oplog) for active data. When the SSD tier utilization exceeds recommended thresholds (typically above 75-80%), the system must aggressively destage data to the slower HDD Capacity tier to free up space for incoming writes.

This destaging process and the lack of available SSD space for the active working set (WS) force read and write operations to be served from the slower Capacity tier (HDD), resulting in significantly higher latency and "sluggish" desktop performance. The vCPU ratio (4:1) and Host CPU (< 40%) are well within healthy limits, ruling out CPU contention.
