Overview

Ampere® Altra® processors are designed from the ground up to deliver exceptional performance for Cloud Native applications such as NGINX. With an innovative architecture that delivers high performance, linear scalability, and amazing energy efficiency, Ampere Altra allows workloads to run in a predictable manner with minimal variance under increasing loads. This enables industry leading performance/watt and a smaller carbon footprint for real-world workloads such as NGINX.

Google Cloud offers the cost-optimized Tau T2A VMs powered by Ampere Altra processors for scale-out Cloud Native workloads in multiple predetermined VM shapes – up to 48 vCPUS per VM, 4 GB of memory per vCPU, up to 32 Gbps networking bandwidth, and a wide range of network-attached storage options. These VMs are suitable for scale-out workloads such as web servers, containerized microservices, data-logging processing, media transcoding, and Java applications.

NGINX is an open-source, high-performance, HTTP server that can also be used as a reverse proxy, load balancer, mail proxy, and HTTP cache. It uses a sophisticated event-driven architecture that allows it to scale to hundreds of thousands of concurrent connections on modern hardware. NGINX is the most popular web server among high-traffic websites as of 2021, with a 33.8% market share, according to W3Techs. 

Results and key benefits

The Google T2A VMs powered by Ampere Altra processors deliver a compelling performance in a variety of NGINX web server configurations, including a TLS-enabled server configuration used in our tests. The web server sends a static file for every request from the load generator over HTTPS. Our metric for performance is the throughput (requests/seconds) with the p.99 latency under 5 ms.

Fig.1: NGINX Performance On Google Cloud T2A Standard 32 Virtual Machines Powered by Ampere® Altra®

The Ampere Altra-based Google Cloud T2A VMs outperform their legacy x86 VM counterparts. The performance results shown in Figure 1 displays that the T2A VMs are 15% more performant than the N2 VMs and roughly on par with the N2d VMs.

Price-performance represents a big portion of the Total Cost of Ownership (TCO) for cloud developers and is an important consideration for large-scale deployments in the cloud. The T2A VMs offer 45% better price-performance compared to the N2 VMs and 11% compared to the N2D VMs.

Benchmarking Configuration

In our tests, NGINX was hosted on 32 vCPU VMs. We compared the Ampere Altra-based GCP T2A VMs to the Intel® Xeon® Ice Lake-based N2 and the AMD EPYC™ Milan-based N2D VMs. Like most open-source software, NGINX is natively supported on AArch64 and we used the corresponding package manager provided by the OS to install it on all the server VMs. To a client request, the NGINX server serves a static file compressed with gzip over HTTPS. WRK is used as a load generator running on a separate 32 vCPU VM. Performance is measured in requests per second under a Service Level Agreement (SLA). We use no more than 5 ms for the 99th percentile latency (p.99) as the SLA. We configured the thread count and concurrency levels to achieve maximum throughput while keeping the p.99 latency under 5 ms. The client and server VMs were configured to be part of the same subnet to achieve the best network throughput.
