GitLab on Graviton2: 23% cheaper, 36% higher performance

What this post added

This post details the performance benchmarking of GitLab's 10,000 user reference architecture and GitLab Runner on AWS Graviton2 (Arm64) instances compared to x86-based instances. It quantifies cost savings (up to 23%) and performance gains (up to 36%) for the GitLab application and Runner, respectively. It describes the testing methodology using the GitLab Performance Tool and the GitLab Environment Toolkit, and presents CPU utilization graphs from Prometheus and Grafana to illustrate performance under load.
