This blog post dives into a head-to-head performance comparison of two leading contenders: AWS Graviton4 (powering AWS r8g instances) and Google Axion (powering GCP Axion instances), both built on the advanced Arm Neoverse-V2 architecture. We'll examine their performance with Valkey 8.0.1, a popular in-memory data store. The Contenders: AWS Graviton4 and Google Axion AWS Graviton and Google Axion represent the latest generation of ARM-based server processors from Amazon and G

We conducted SPDK bdevperf tests on an AWS EC2 r8gd.metal-24xl instance, focusing on single CPU core performance under high I/O load. Our objective was to demonstrate a CPU-bound workload. Results show low I/O wait and high CPU utilization, confirming the CPU is the limiting factor. The 2-disk configuration achieved the highest throughput, indicating a CPU saturation point. 1. Performance Results Summary  (100-second duration) Below is a consolidated view of our 100-second bd
