Benchmark Comparison: Hetzner’s CAX31 vs CPX31 – ARM vs x86

This is the batte between ARM and x86. I’m using Hetzner Cloud VPS, as it has the hourly pricing, which is suitable for short time benchmarking.

I picked the CAX31 and CPX31 as it has the closest pricing, and i don’t use Hetzner CX31 (Intel) as it’s slower than CPX31.
