At 3k concurrent sandboxes, ARM beats Zen 5 on 3 of 4 agent workloads
mattturck · x · 2026-09-02
JukicVedran benchmarked ARM vs amd64 (Zen 5) running identical agent sandboxes from 1 to 3k concurrent, covering the four tasks agents actually do in a Daytona sandbox: the coding-agent loop, local disk work, local analytics, and a sequential numeric loop. Both architectures held throughput as sandboxes scaled, but at high concurrency ARM was faster on three of the four workloads — a useful signal for agent infrastructure architecture choices.
