Getting to the Core: Benchmarking Cloudflare’s Latest Server Hardware

What this post added

This post details the design and benchmarking of Cloudflare's new 'Core Compute 2020' (AMD-based) and 'Core Storage 2020' (Intel-based) server hardware. It covers configuration changes from previous generations, including the move to single-socket CPUs, NVMe SSDs, and improved memory speeds. Benchmarking results for both synthetic and production workloads (Kubernetes, Kafka, CSAM Scanning Tool, ClickHouse) demonstrate significant performance improvements in areas like storage throughput, IOPS, latency, and CPU frequency sustainment, leading to potential cost savings and space efficiency.
