Standard and High CPU Virtual Machines Using Intel® QAT Outperformed AMD EPYC Processor-Based VMs Without Intel® QAT
Providing safe, encrypted network connections using SSL/TLS is a smart business move because it puts your consumers at ease about sending their data over the Internet. NGINX is an open-source web server application that serves as a reverse proxy, load balancer, and mail proxy. If your company runs NGINX web servers on Google Cloud, you can improve performance dramatically by choosing N2 VMs featuring 3rd Gen Intel® Xeon® Scalable processors.
Installing Intel® QuickAssist Technology (Intel® QAT) on Google Cloud N2 Virtual Machines can boost NGINX web server performance. Intel® QAT and Intel® QAT Engine (OpenSSL Engine) use vectorized instructions to speed cryptographic operations and allow more users to connect at a time, which in turn speeds hardware and software. We tested NGINX performance for four series of VMs: N2D and T2D, both powered by AMD EPYC processors, and Standard N2 VMs and High CPU N2, both featuring 3rd Gen Xeon® Scalable processors. Our results show that choosing one of the N2 VMs featuring 3rd Gen Xeon® Scalable processors and adding Intel® QAT would yield the best performance for your NGINX workloads.
VMs Featuring 3rd Gen Xeon® Scalable Processors with Intel® QAT Improved Performance at Every VM Size
Figure 1 shows results at smaller vCPU counts. Using Intel® QAT with N2 VMs with 3rd Gen Intel® Xeon® Scalable processors boosted NGINX performance significantly over both AMD EPYC-processor-based VMs. N2 VMs with Intel® QAT achieved a connection rate up to 2.99 times that of N2D VMs at 4 vCPUs and up to 2.98 times that of N2D VMs at 8 vCPUs.
N2 VMs featuring 3rd Gen Intel® Xeon® Scalable processors with Intel® QAT achieved a connection rate up to 2.93 times that of N2D VMs at 16 vCPUs and up to 3.00 times that of N2D VMs at 32 vCPUs. (See Figure 2.)
N2 VMs featuring 3rd Gen Intel® Xeon® Scalable processors with Intel® QAT achieved a connection rate up to 2.91 times that of N2D VMs at 48 vCPUs and up to 2.54 times that of N2D VMs at 64 vCPUs. (See Figure 3.)
Google Cloud N2 VMs featuring 3rd Gen Intel® Xeon® Scalable processors and using Intel® QAT delivered much stronger NGINX performance than both N2D and T2D VMs with AMD EPYC processors.
