Get up to 49% Better Microsoft® SQL Server Online Transaction Processing Performance by Selecting Microsoft Azure® Dsv5 Virtual Machines Rather Than Dsv4 Virtual Machines

Microsoft SQL Server:

  • Experience 49% more OLTP performance with 8-vCPU Dsv5 VMs vs. Dsv4 VMs.

  • Experience 28% more OLTP performance with 16-vCPU Dsv5 VMs vs. Dsv4 VMs.

VMs Featuring 3rd Gen Intel® Xeon® Scalable Processors Achieved More New Orders per Minute than VMs with Previous-Gen Processors

Whether you use online transaction processing (OLTP) workloads for online ordering, customer service management, financial transactions, or something else, strong performance is vital. Making your customers or employees wait for a sluggish system to respond can be a recipe for annoyance.

If your company is seeking a public cloud solution to host your OLTP workloads, be aware that performance can vary considerably from one instance to another, even from the same cloud provider. As one example, the Microsoft Azure Dsv5-series VMs enabled by 3rd Gen Intel® Xeon® Scalable processors can deliver greater performance than Dsv4 VMs enabled by 2nd Gen Intel® Xeon® Scalable processors.

In benchmark tests of these two series of Microsoft Azure VMs, Dsv5 VMs delivered up to 49% better Microsoft SQL Server OLTP performance. That advantage can help your customers place their orders more efficiently and help your employees finish their work sooner.

Better Performance on Smaller Instances

TPROC-C is an opensource OLTP workload that is part of the HammerDB benchmarking tool. It generates a metric of new orders per minute (NOPM) that allows users to compare database performance. (Note that TPROC-C results are not comparable to official TPC-audited results.) We used TPROC-C is to test multiple sizes of two Azure series. As Figure 1 shows, by choosing 8-vCPU Dsv5 VMs enabled by 3rd Gen Intel® Xeon® Scalable processors over the same size Dsv4 VMs enabled by older processors, you could enjoy 49% better performance. Selecting 16-vCPU Dsv5 VMs over Dsv4 VMs featuring the previous-generation processors would allow you to reap 28% more the performance.

Better Performance on Larger Instances

As Figure 2 shows, by choosing 32-vCPU Dsv5 VMs enabled by 3rd Gen Intel® Xeon® Scalable processors you could enjoy 19% more performance than you’d see with 32-vCPU Dsv4 VMs enabled by 2nd Gen Intel® Xeon® Scalable processors. With the largest VMs we tested, with 48 vCPUs, choosing the Dsv5 series would give you 23% better performance than you’d get with the Dsv4 series VMs.

Conclusion

Regardless of the type of OLTP applications you run, choosing cloud instances that allow them to process more orders per minute can translate to more satisfied users. Our testing showed that opting for Azure Dsv5 instances with 3rd Gen Intel® Xeon® Scalable processors can allow your applications to execute orders at a rate up to 49% higher than that of Dsv4 instances with 2nd Gen Intel® Xeon® Scalable processors.
