VMs Featuring 3rd Gen Intel® Xeon® Scalable Processors Handled More New Orders Per Minute Than VMs with Previous-Gen Processors

Companies rely on online transaction processing (OLTP) workloads for a range of activities, from retail sales to ordering to customer service management. Choosing cloud instances that process these transactions at a speedy clip is a great way to improve the experience for your customers and employees. If you’re shopping for a public cloud solution to host your OLTP workloads, keep in mind that instances can perform very differently depending on their underlying hardware. For example, Microsoft Azure Esv5-series VMs featuring 3rd Gen Intel® Xeon® Scalable processors can outperform Esv4 VMs enabled by 2nd Gen Intel® Xeon® Scalable processors.

When we conducted benchmark tests of these two series, we learned that Esv5 VMs enabled by 3rd Gen Intel® Xeon® Scalable processors delivered up to 48% better Microsoft SQL Server OLTP performance. That advantage could deliver a smoother experience for your users.

Comparing Smaller Azure VMs

Our tests used TPROC-C, an open-source OLTP workload from the HammerDB benchmark, to measure the performance of multiple sizes of two Azure series. TPROC-C generates a metric of new orders per minute (NOPM). (Note that TPROC-C results are in no way comparable to official TPC-audited results.) As Figure 1 shows, an organization that chose 8-vCPU Esv5 VMs enabled by 3rd Gen Intel® Xeon® Scalable processors would enjoy 48% better performance than one that chose the same size Esv4 VMs enabled by 2nd Gen Intel® Xeon® Scalable processors. For VMs with 16 vCPUs, the Esv5 VMs would deliver 33% more performance than the Esv4 VMs featuring the previous-generation processors.

Comparing Larger Azure VMs

In Figure 2, we show how larger VMs stack up. By opting for 32-vCPU Esv5 VMs enabled by 3rd Gen Intel® Xeon® Scalable processors rather than 32-vCPU Esv4 VMs enabled by previous-generation processors, you could enjoy 22% higher performance. Selecting 48-vCPU Esv5 VMs could allow you to reap 12% better performance than the Esv4 VMs would deliver.

Conclusion

Our testing revealed that AWS Esv5 instances with 3rd Gen Intel® Xeon® Scalable processors can allow your applications to perform at a rate up to 48% better than that of Esv4 instances with 2nd Gen Intel® Xeon® Scalable processors. Running your MySQL OLTP workloads on cloud instances that support a higher rate of orders per minute is a smart business move that can reduce wait time—and the frustration that accompanies it—for your customers and employees.
