A single vCPU is likely causing a bottleneck, limiting the VM's ability to process I/O requests efficiently.
* Option D (Increase the VM's number of vCPUs) is correct:
* Windowsrequires sufficient CPU resourcesto handle disk and network operations.
* Adding more vCPUs allows the VM to process more I/O operations simultaneously, improving performance.
* Option A is incorrect:
* AdditionalvSCSI controllers are only useful for very high disk I/O workloads.
* Option B is incorrect:
* Balance-TCP applies to network traffic, not storage performance.
* Option C is incorrect:
* CVM resources do not directly affect individual VM performance.
