Latencysensitivity features of ESXi September 29, 2016 joseph VMWare In ESXi 5. 5 there was a latency sensitive feature added to the web client. This feature applies to individual virtual machines. It was specifically added for latency sensitive applications. VMware full recommendations for latency sensitive applications can be foundYou can adjust the latency sensitivity of a virtual machine to optimize the scheduling delay for latency sensitive applications. ESXi is optimized to deliver high throughput. latency sensitive applications vmware

However, certain applications that are extremely latencysensitive would still be affected by the overhead due to strict latency requirements. In order to support virtual machines with strict latency requirements, vSphere 5. 5 introduces a new perVM

latency sensitive applications

Low latency application were still running on physical until now, not virtualized. With the latest enhancements made in vSphere 5. 5 and having the possibility to give exclusive access to physical resources and bypassing the virtualization layer. Some applications are inherently highly latency sensitive, and cannot afford long vMotion times. VMs running such applications are termed as being Latency Sensitive. These VMs consume resources very actively, so vMotion of such VMs is often a slow process. Such VMs require special care duringlatency sensitive applications vmware For best performance of latencysensitive applications in guest OSes, all vCPUs should be scheduled on the same NUMA node and all VM memory should fit and be allocated out of the local physical memory attached to that

VMware vSphere ensures that virtualization overhead is minimized so that it is not noticeable for a wide range of applications including most business critical applications such as database systems, Web applications, and messaging systems. vSphere also supports well applications with millisecondlevel latency constraints, including VoIP latency sensitive applications vmware You can adjust the latency sensitivity of a virtual machine to optimize the scheduling delay for latency sensitive applications. ESXi is optimized to deliver high throughput. Abstract. This paper investigates the overhead of virtualizing latencysensitive applications on the VMware vSphere platform. Specifically, request response workloads are used to study the responsetime overhead compared to Additionally, VMware is claiming is can offer a better performance for latency sensitive applications. NUMA Node Affinity NUMA affinity basically assigns a VM to a NUMA node. This can be monitored with ESXTOP. I would not recommended this until it has been determined that NUMA latency is an issue. We say this because each application
