User are complaining that web application hosted on a Nutanix cluster are running slow. After reviewing the performance metric, it is determined that the CPU Ready time is high in the cluster.

What entity is impacted by CPU ready time?

AOplog

BNIC

CvDisk

DVM

Show Suggested Answer

Suggested Answer: A

The oplog is a critical component of the Nutanix distributed storage fabric and can be impacted by high CPU Ready time. When the CPU Ready time is high, there can be delays in writing data to the oplog, resulting in slower overall cluster performance. Additionally, high CPU Ready time can also lead to increased write amplification, further reducing I/O performance.

This is a classic case of the VMs being the MVPs (Most Valuable Procastinators) in the cluster. High CPU ready time means they're just sitting around waiting for their turn to shine.

CPU ready time, eh? Sounds like the VMs are doing their best impression of a traffic jam on the expressway. The VMs are definitely the ones feeling the slowdown.

Hmm, high CPU ready time, huh? Looks like the VMs are waiting in line for their turn on the CPU. I'd say that's the entity that's getting the short end of the stick.

I don't think so, the VM is more likely to be impacted.

But could it also be the vDisk that is impacted?

CPU ready time? Sounds like the VMs are doing some heavy lifting, but they're stuck in the waiting room. I'd bet my last dollar it's the VMs that are feeling the pinch.
