Hetzner

Hands‑on guide for Hetzner dedicated servers: use an NVMe SSD with Bcache to accelerate a 14×22 TB HDD RAID array on Debian 12. Covers enabling the kernel module, installing bcache-tools, formatting and binding backing/cache devices, tuning cache modes, filesystem setup, fstab auto-mount, plus lsblk verification and YABS Fio benchmarks to eliminate I/O stalls during large downloads.

Hetzner’s auction servers are an incredible deal: for under €60 you can grab a top-spec Ryzen 9 5950X dedicated box. This guide walks through choosing RAID, entering Rescue mode, using installimage for fast OS deployment, plus common pitfalls and billing gotchas so you can enjoy high-end compute on the cheap.

This post compares Hetzner CAX31 (ARM) and CPX31 (x86) instances using PassMark, Geekbench 5/6, UnixBench, and various Phoronix Test Suite workloads (PostgreSQL, Nginx, Apache, PHP, Redis, MariaDB, 7-Zip), plus fio disk benchmarks. It analyzes single-core vs multi-core performance and price-to-performance, concluding that x86 wins in single-core, while ARM offers stronger multi-core throughput and better overall value, with selection advice for different workloads.
