VMware CPU Co-Stop and SQL Server Performance (via Convergence of Data and Infrastructure)
VMware CPU Co-Stop and SQL Server Performance
Not too many people know about the intricacies of virtualization CPU scheduling and its impact on the performance of the VMs, so application owners out there – listen up! I’ve written about Ready Time (VMware ESXi) / Wait Time Per Dispatch (Microsoft Hyper-V) in the past, but a different challenge arises with VMs that have large vCPU count footprints. It’s called CPU Co-Stop, and it can devastate your application’s performance in a VM.
