Developer VDI users are complaining about performance issues and states that tasks are taking longer...

In virtualization performance troubleshooting, CPU Ready % is a critical metric that indicates the percentage of time a virtual machine was ready to execute a thread but had to wait for the hypervisor to schedule it on a physical CPU core.

According to standard Nutanix and AHV performance guidelines, a CPU Ready value above 5% per vCPU is considered a leading indicator of CPU contention (oversubscription) and performance degradation. While the overall host CPU Usage appears low (18%), the high CPU Ready (6.5%) suggests that specific VMs are fighting for scheduling slots, causing the latency ("tasks taking longer") reported by the users. The other metrics (IOPS, Storage Usage) are well within normal operating parameters.
